Proton's half life (Energy-dependent)

Proton's half life has a lower estimated bound in 10^33 years aprox. This is due to the enormous mass of the X boson, predicted by some GUTs. So my question is: if the free proton is in a high energy state, it has more energy (ready to be "used") and thus it would be easier to create the X boson needed. Is this implying a energy-dependent half life? If so, has this dependence been calculated somewhere? I'd love to have some references if possible. Sorry for my english and thanks.

• There's a misconception here: it is the mass (a Lorentz-invariant quantity) which can be "used" to create particles in a decay. Alternatively you may think of it as the energy in the centre-of-momentum frame. The relation $E=mc^2$ only works at rest. More generally it is $E^2 = p^2c^2 + m^2c^4$. – dukwon Apr 24 '17 at 9:16
