SUMMARY

The discussion centers on the phenomenon of quark confinement during the period of approximately 10-12 to 10-5 seconds after the Big Bang. It is established that quarks can bind into baryons like protons and neutrons when the average energy of photons (kT) drops below 1 GeV. The user questions how a Bottom quark (5000 MeV) and a Strange quark (540 MeV) can bind given their combined rest mass exceeds 1 GeV. The inquiry emphasizes the need for clarification on the relationship between rest mass, relativistic momentum, and the threshold energy for quark confinement.

PREREQUISITES
  • Understanding of quark properties and classifications
  • Familiarity with relativistic physics and energy-mass equivalence
  • Knowledge of quantum chromodynamics (QCD) principles
  • Basic grasp of particle physics terminology and concepts
NEXT STEPS
  • Research quantum chromodynamics (QCD) and its role in quark interactions
  • Study the concept of relativistic mass and its implications in particle collisions
  • Explore the mathematical framework of binding energies in particle physics
  • Investigate analogies used in explaining particle confinement phenomena
USEFUL FOR

This discussion is beneficial for particle physicists, students of quantum mechanics, and anyone interested in the fundamental interactions of subatomic particles, particularly those studying quark dynamics and confinement.

Greetings,

I've read that Quarks became confined and able to bind into baryons like protons and neutrons in the Period of ~10*-12seconds -to- ~10*-5seconds. Its been stated that as the average photon's energy in this period (kT) dropped below about 1 GeV, that quarks could finally bind to each other since collision energies were sufficiently weak to allow such binding...

My Question then is this, given that the 6 known Quarks have these energies:

Up 340MeV
Down 340MeV
Charm 1500MeV
Strange 560MeV
Top 174000MeV
Bottom 5000MeV

How is it possible for, say, a Bottom and Strange Quark to bind if their combined rest masses are already well above 1 GeV (they are 5560MeV combined)? Also, this doesn't even consider their Relativistic momentums which would make their masses much greater as they approach velocities near C.

If anyone could explain why 1 GeV is the apparent threshold for Quark confinement in terms of the Rest Masses of these Quarks and their Relativisitc collision energies, I would greatly appreciate it. If you could provide a good analogy in conjunction with the mathematical framework and formulas, even better.

Thank you kindly,

Paul
