Actually you got it exactly wrong. The particles move throgh a Higgs field.
The mass of the particle is inversely proportional to the strength of the
force. So a graviton is in fact the most massive particle there is.
To accelerate a particle to get enough energy to produce graviton's
you would need a 1 light year long accelerator.
So their energy is positively huge.
The idea behind this is that in any energy field virtual particles are
continuously
produced due to the fact that space contains energy. Since the amount of
energy needed to create a graviton is very high the chance of one being
produced is very small.
