Special relativity - particle collisions

  1. May 26, 2012 #1
    1. The problem statement, all variables and given/known data

    2 protons collide at centre of mass energy of 7 TeV and produces a higgs with mass 100GeV and 2 protons:

    pp -> ppH

    calculate maximum energy of both protons in the final state


    3. The attempt at a solution

    Assuming higgs is produced at rest in lab frame (so protons have max energy) and conserving 4-momentum i just get 6.9TeV which is just the energy difference between the centre of mass energy and the higgs rest mass energy.

    Is this right?

    Yep. That is right. You have calculated the energy of both protons added together. The question asked "calculate maximum energy of both protons in the final state" So be careful, this might mean the energy of each of the final protons(individually, not added together)
