Rapiditiy and center of mass energy

  1. Mar 9, 2010 #1
    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!

    There are lots of kinematic relationships. It's like saying "is there a relationship between an object's position and it's energy?" Sure...but the exact relation depends in the exact situation.
