Energy difference between accelerated particles and Jets

Click For Summary
SUMMARY

The discussion centers on the energy dynamics of jets produced in high-energy collisions at the Large Hadron Collider (LHC), where protons are accelerated to 7 TeV. Jets, which are sprays of particles resulting from these collisions, possess significantly less energy than the colliding protons. The minimum striking force required to disperse a proton is a few GeV, as the energy is conserved and cannot be liberated in proton-proton collisions. The conversation also touches on the complexities of energy distribution and conservation laws in particle physics.

PREREQUISITES
  • Understanding of particle physics concepts, particularly proton collisions
  • Familiarity with high-energy physics experiments, specifically at the LHC
  • Knowledge of conservation laws in physics, including baryon number conservation
  • Basic grasp of quantum chromodynamics (QCD) and jet formation
NEXT STEPS
  • Research "jet energy resolution" and the Jet Plus Track (JPT) algorithm
  • Study "quantum chromodynamics" and its role in particle interactions
  • Explore "hard scattering" processes in proton-proton collisions
  • Investigate the implications of "baryon number conservation" in particle physics
USEFUL FOR

This discussion is beneficial for theoretical physicists, particle physicists, and students interested in high-energy physics and the mechanics of particle collisions at accelerators like the LHC.

I should not find WHY your "argument" is wrong, you should tell me why it is true.
You already found out yourself why my argument makes sense.

ansgar said:
I mean, I work with this everyday, the quantum field theory perscription of the proton works delicate with data.
Working doesn't mean a thing if the work you do is useless.

ansgar said:
You have just read about the Higgs field in some popular science book and think that it would be a nice thing to talk about or so... I mean you could say that the energy is released into the Dark Energy or whatever, or the pink ghost field... just because one uses science objects does not make it science..
Instead of whining, I think it would be more helpful if you seriously considered the suggestions I made, and see if there is any sense in them or not. Now that would be something to work on.

ansgar said:
I still have NO clue what you want to learn from this thread, do you want to learn how proton-proton collisions work and how jets are formed or do you have your own home-made theories which you seek confirmation for?
Indeed I look for confirmation if their could be energy released during a Pb-Pb collision.

ansgar said:
Your last post is speculative and against the forum guidelines.
No, it is not speculative, you just said that I haven't got the right to make any suggestions, because I supposedly haven't got a degree in physics, isn't that a little bit pretentious.

ansgar said:
If you smash two protons with centre of mass energy equal 2GeV the energy from the collected "pieces" is also 2GeV, why are you argue against that? Are there papers in journals out there suggesting for energy loss/release in proton-proton collisions which gave you this idea?
If I found papers suggesting energy release from Pb-Pb collisions, I wouldn't waste time question such an idea. That's why I'm posing the question over here to see what others think, isn't that the purpose of a forum, to exchange ideas.

ansgar said:
Why is this hard to understand?
What I don't understand is, why you said yourself that "the mass of the sum of particles is different then proton of course", and now you start dismissing the idea.

ansgar said:
Secondly, you seem to have forgot HOW the jets are formed, they are not formed by quark decays but from hadronization and the proton do not contain top quarks (only virtual sea top quarks, with parton distribution function almost equal to zero at all Q^2 ) so why talking in terms of that?
I just pointed out that a free quark decays and one in a proton doesn't. It's like putting food in a fridge, there is energy needed to keep it from rotting, or must I say decaying.

ansgar said:
why don' t ask for references in particle physics which suits your background in physics?
Good question, because you don't seem to be able to provide any sensible answers.

This is turning into speculation; I am closing this thread.
