Lorentz transformation of delta function

For two body decay, in CM frame, we know that the magnitude of the final particle momentum is a constant, which can be described by a delta function, ##\delta(\vec{p^*}\vec{p_0^*})##, ##\vec{p_0^*}## is a constant.
When we go to lab frame (boost in z direction), what's the Lorentz transformation of the delta function? regards!

What do you mean by "which can be described by a delta function" ?

Maybe my example of two body decay is not so suitable, but my question is just for mathematics, that is the Lorentz transformation of ##\delta(\vec{p}\vec{p_0^*})##

Chenkb,
Are talking about a distribution function in the momentum space, and about how this function might evolve with an interaction? Are you considering 3momentum or 4momentum?
