## Main Question or Discussion Point

Hey Folks,

i just wondered if there is a direct connection between the rapidity parameter y and the center of mass energy squared s (for example in the case of two colliding massless particles (aka high energy approx). I tried googling it, but failed to find any satisfying answer.

Thank you in advance!
