Special relativity - particle collisions

Click For Summary
SUMMARY

The discussion centers on a particle collision scenario where two protons collide at a center of mass energy of 7 TeV, producing a Higgs boson with a mass of 100 GeV. The correct calculation for the maximum energy of each proton in the final state, assuming the Higgs is produced at rest in the lab frame, is determined to be 6.9 TeV. This value represents the total energy of the two protons minus the rest mass energy of the Higgs boson. Participants emphasize the importance of interpreting the question correctly, as it specifically asks for the energy of each proton individually rather than their combined energy.

Homework Statement



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


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)
