Hi,
In the derivation of scattering amplitudes (e.g. page 94 in http://kcl.ac.uk/content/1/c6/06/20/94/LecturesSM2010.pdf ) does anyone have a clue as to how to prove that the momentum uncertainty element
(\delta p)^3/E
is Lorentz invariant? I know how to do it for the measure d^3p/E, but I am not sure how to proceed for the given (non-infinitesimal) element.
Thank,
P
