Hi,
I'm recently reading "Particle Physics in the LHC Era" and there is a part about the phase space factor that confuses me. When giving the Lorentz invariant phase space, they wrote:
d3p / 2E = θ(E) δ(p2 - m2) d4p
This is very confusing as it equates a three dimensional differential to a four dimensional one. Is there anything I didn't take into account?
Thank you!
