Hi all, Does anybody here know roughly what the maximum "physics energy" is for an LHC proton-proton collision? Since protons are composite particles the collisions are actually between individual quarks/gluons/whatever, and I'd like to get an idea of the "inefficiency" compared to the beam proton energy. I couldn't see this in a quick look at Wikipedia, probably because I'm not sure what the technical terms would be! Thanks |

Take a look at this dokument: https://cds.cern.ch/record/2809109/files/CERN-Brochure-2021-004-Eng.pdf Especially pages 12 and 21. |

Thanks for that - I'll have to read it through properly. It's nice to see LHC experiments other than the big four get a mention. For reference., p21 answers a similar question I think: Lead-Lead has a total of 1150 TeV available but there is actually only 5.02 TeV available to the colliding pair of nucleons within; possibly I'm misunderstanding the physics but shouldn't there be a similar downshift between the overall proton(nucleon) energy and that of the actual colliding constituents? |
