"Higgs In Space" or Where's Waldo?
[[Mod. note -- Two comments:
1. This article was submitted to sci.physics.research (only), but an identical article was recently submitted to (and approved by the moderator and hence posted to) sci.astro.research. Please don't duplicate-submit like this -- crosspost instead! [That is, if you want your article to appear in both s.p.r and s.a.r, edit the "Newsgroups:" line of your submission to say "Newsgroups: sci.physics.research,sci.astro.research". Note that there is NOT a space after the comma!] Crossposting allows news-reading software to "know" that the same article appears in both places, so (for example) if you (a human reader of both newsgroups) have read the article in one of the newsgroups, the software can avoid showing it to you again in the other newsgroup. Similarly, crossposting ensures that any followups should be seen by readers of both newsgroups. Moderators will often reject articles which are identical to those already posted elsewhere (telling the author to crosspost instead), but in this case I'm approving this article. However, I've taken the liberty of editing the "Newsgroups:" header to make this article crossposted to both newsgroups. Hopefully any followup discussion thread will then be properly crossposted... 2. The paper being discussed is arXiv:0912.0004 C.B. Jackson, Geraldine Servant, Gabe Shaughnessy, Tim M.P. Tait, Marco Taoso "Higgs in Space!" Sean Carroll describes this paper as Winner of the coveted "Best Paper Title Among Today's arXiv Postings." at http://blogs.discovermagazine.com/co...iggs-in-space/ -- jt]] A new submission to hep-th at arxiv.org presents an interesting challenge: Sort of a 'Where's Waldo?' except that instead of 'Waldo' we are hunting for a Definitive Scientific Prediction. Here is the paper: http://arxiv.org/PS_cache/arxiv/pdf/...912.0004v1.pdf We remember that a Definitive Prediction is: 1. feasible 2. made prior to the tests 3. quantitative [an exact number or very restricted range of numbers] 4. non-adjustable [fudging and excessive hedging not allowed] 5. unique to the theory being tested We also remember that the mass of the putative Higgs particle is highly uncertain, except for a reasonable lower limit already set by previous testing. There is no definitive upper limit that cannot be circumvented, to my knowledge. Lattice theories can generate very heavy putative Higgs particles. So it would appear that the predicted putative Higgs masses might vary by factors of 3 or more. Given the above, can anybody identify a truly Definitive Scientific Prediction by which we might define this paper as science, as opposed to effectively untestable pseudoscience?

"Higgs In Space" or Where's Waldo?
[Moderator's note: Irrelevant quoted text snipped. -P.H.]
A new submission to hep-th at arxiv.org presents an interesting challenge: Sort of a 'Where's Waldo?' except that instead of 'Waldo' we are hunting for a Definitive Scientific Prediction. Here is the paper:http://arxiv.org/PS_cache/arxiv/pdf/...912.0004v1.pdf We remember that a Definitive Prediction is: 1. feasible 2. made prior to the tests 3. quantitative [an exact number or very restricted range of numbers] 4. non-adjustable [fudging and excessive hedging not allowed] 5. unique to the theory being tested We also remember that the mass of the putative Higgs particle is highly uncertain, except for a reasonable lower limit already set by previous testing. There is no definitive upper limit that cannot be circumvented, to my knowledge. Lattice theories can generate very heavy putative Higgs particles. So it would appear that the predicted putative Higgs masses might vary by factors of 3 or more. Given the above, can anybody identify a truly Definitive Scientific Prediction by which we might define this paper as science, as opposed to effectively untestable pseudoscience? Yours in traditional science and its time-honored methods, RLOwww.amherst.edu/~rloldershaw Well, we can pick ranges for where the Higgs may exist, then look for it there. I know Tomasso Dorigo had a post on his new blog about this exact topic a week or so ago. Here is the post: http://www.scientificblogging.com/qu..._tevatron_hig= gs_limits_got_worse_115_gev_excess_growing Tomasso hopes for a light 115 GeV Higgs, and some MSSM models predict that. Other MSSM models predict much heavier Higgs, 160+ GeV; other non-MSSM models predict truely massive (720 GeV) Higgs, while some of the more convoluted models predict multiple Higgs. Some scientists, myself, and Stephen Hawkings (AFAIK), prefer not to see a Higgs at all. Stephen because it would be more "interesting", and myself because I have a feeling deep in my gut that a Higgs will complicate the relationship between inertial and gravitational mass, whatever that may be. The search for the Higgs, and other particles, relies much more on data from experiments to be conducted, rather then experiments already done. This lack of data is why we cannot nail down the Higgs right now, and all these predictions would fall under "Definite Scientific Prediction". They all make a prediction about the range of the Higgs, and this prediction can be tested. (I think I wrote about this issue on my blog some time ago, but a quick google search brings up nothing. If you want to look, go ahead, but I make no statements of accuracy, nor of existence. http://www.aitj-co.com/gcsgz5/blog) |

Forgive if I ask this: is that paper really meant seriously? (To me it looks like kind of elaborated parody.) Is that the way science works? They combine three speculative items - Higgs, WIMPs and Dark Matter - and combine them to super-speculation about dark matter annihilation. Quote: "We consider the possibility that the Higgs can be produced in dark matter annihilations, appearing as a line in the spectrum of gamma rays at an energy determined by the masses of the WIMP and the Higgs itself" TH |

One of the authors contacted me, anonymously of course, and criticized me for having advocated sobriety at their analytical bacchanal. He/she tried to convince me that they did make predictions, although about four of the variables are completely adjustable, and virtually any gamma-ray line found by the Fermi team, arising from any number of physical causes, could be interpreted as evidence for some variation of their "Higgs annihilation toy idea". Only Definitive Predictions [prior, testable, unique, non-adjustable and rigorously quantitative] count in science. Pseudo-predictions [towers of if/then reasoning, adjustable variables, after-the-fact reasoning, unfeasible, non-unique to the theory being tested, etc.] are not scientific. They can seriously mislead and divert attention from serious science. Theorists should feel free to speculate wildly in search of useful ideas, but the broader physics community should realize that this stuff is pseudoscience until it can produce Definitive Predictions. The physics community, and especially editors of scientific publications, need to make critical distinctions between science and pseudoscience. If the distinction continues to be ignored, science is in jeopardy. This is something that those who value science highly cannot tolerate. Junk-bond science is not acceptable.

But if a theory makes a definitive prediction, and then this prediction is ruled out by reasoning in which no-one can point to any logical gaps, then the originator of that theory should acknowledge this and move on, and not continue to cite some obscure/outdated/crackpot/not-taken-seriously-for-other-reasons reference in support of his discredited theory, but should acknowledge defeat and move on (like, say, Bondi and Morrison after the steady-state cosmology was ruled out).

Do I make myself clear enough on this point? No. There are no "bare facts". By reasoning I mean constructing a theory which makes predictions different from those of the first theory and having these predictions confirmed by observation. In other words, by reasoning that the first theory predicts something, and another theory predicts something else, and it is something else which is observed. If the prediction is falsified empirically in a definitive manner, then and only then should the author accept nature's verdict, and further, not resort to smoke, mirrors, "adjustments" to the theory, mendacity, etc. Yes, but "falsified empirically" implies some reasoning about what the theory predicts. |

Why the arbitrary restriction to the last three weeks and in scope? If you just want to see examples of "Definitive Predictions", any kind should do, right? Nonetheless, even keeping close to your criteria, there are plenty of examples. Take a look at this arXiv search query of the gr-qc category, concerning definite predictions of gravitational waveforms from binary astrophysical sources (which are just a subset of all possible sources): http://arxiv.org/find/gr-qc/1/AND+ti.../0/1/0/all/0/1 Once gravitational wave detectors start producing reliable observations, all of these models will go through an honest weeding, as they should.

Just out of curiosity: Have you seen any good Definitive Predictions published in any papers posted to astro-ph or hep-phenomenology or hep- theory at arxiv.org since, say, X-mas? Here are two definitive predictions (I see no need for upper case here). The first doesn't meet your time window, but is otherwise a nice case: http://arxiv.org/abs/0901.3779 Authors: Authors: Todd A. Boroson (NOAO), Tod R. Lauer (NOAO) Title: A Candidate Sub-Parsec Supermassive Binary Black Hole System Abstract: We identify SDSS J153636.22+044127.0, a QSO discovered in the Sloan Digital Sky Survey, as a promising candidate for a binary black hole system. This QSO has two broad-line emission systems separated by 3500 km/sec. The redder system at z=0.3889 also has a typical set of narrow forbidden lines. The bluer system (z=0.3727) shows only broad Balmer lines and UV Fe II emission, making it highly unusual in its lack of narrow lines. A third system, which includes only unresolved absorption lines, is seen at a redshift, z=0.3878, intermediate between the two emission-line systems. While the observational signatures of binary nuclear black holes remain unclear, J1536+0441 is unique among all QSOs known in having two broad-line regions, indicative of two separate black holes presently accreting gas. The interpretation of this as a bound binary system of two black holes having masses of 10^8.9 and 10^7.3 solar masses, yields a separation of ~ 0.1 parsec and an orbital period of ~100 years. The separation implies that the two black holes are orbiting within a single narrow-line region, consistent with the characteristics of the spectrum. This object was identified as an extreme outlier of a Karhunen-Loeve Transform of 17,500 z 0.7 QSO spectra from the SDSS. The probability of the spectrum resulting from a chance superposition of two QSOs with similar redshifts is estimated at 2X10^-7, leading to the expectation of 0.003 such objects in the sample studied; however, even in this case, the spectrum of the lower redshift QSO remains highly unusual. since published in Natu http://www.nature.com/nature/journal...ture07779.html Their assertion that this is a binary system with an orbital period of ~100 years is implicitly a prediction of its future evolution, and in particular of strong and relatively easily-measured time-dependent Doppler shifts for the two emission-line systems. [N.b. I think, but am not sure, that further research has found other more-prosaic explanations for their observations, but I don't know the details -- this isn't my research area. Typing "J1536+0441" into the "object name" box at http://adsabs.harvard.edu/abstract_service.html yields 15 abstracts. But the outcome 1-year-later doesn't matter for Robert Oldershaw's request: he asked for *predictions*, not for *predictions that are un-refuted 1 year later*.] Here's another "definitive prediction" which *does* fall within Robert Oldershaw's (quite arbitrary IMHO) time window: http://arxiv.org/abs/1001.1426 Authors: M.

Wuchterl Title: Transiting exoplanets from the CoRoT space mission IX. CoRoT-6b: a transiting `hot Jupiter' planet in an 8.9d orbit around a low-metallicity star Abstract: The CoRoT satellite exoplanetary team announces its sixth transiting planet in this paper. We describe and discuss the satellite observations as well as the complementary ground-based observations - photometric and spectroscopic - carried out to assess the planetary nature of the object and determine its specific physical parameters. The discovery reported here is a `hot Jupiter' planet in an 8.9d orbit, 18 stellar radii, or 0.08 AU, away from its primary star, which is a solar-type star (F9V) with an estimated age of 3.0 Gyr. The planet mass is close to 3 times that of Jupiter. The star has a metallicity of 0.2 dex lower than the Sun, and a relatively high $^7$Li abundance. While thelightcurveindicatesamuchhigherlevelof activity than, e.g., the Sun, there is no sign of activity spectroscopically in e.g., the [Ca ] H&K lines. Their equation 1 gives the time at which past eclipses have occured, and is also a definitive prediction of the times at which future eclipses will occur. The orbital parameters given in Table 2 of this paper also provide many other definitive predictions of the future motion of this planet. ciao, -- -- "Jonathan Thornburg [remove -animal to reply]" Dept of Astronomy, Indiana University, Bloomington, Indiana, USA "Washing one's hands of the conflict between the powerful and the powerless means to side with the powerful, not to be neutral." -- quote by Freire / poster by Oxfam |
