Can collision of two protons create multiple antiprotons ?

Click For Summary
SUMMARY

The collision of two protons at an energy of 1.8 GeV can produce multiple protons and other particles, as described by the reaction p + p --> p + p + p + p*. At an increased energy of 3.6 GeV, the reaction p + p --> p + p + p + p + p* + p* is theoretically possible, but the actual outcomes are influenced by conservation laws, particularly energy, charge, and baryon number. In practice, collisions often involve gluons or sea quarks rather than direct proton-to-proton interactions, making head-on collisions rare and the cross section for producing additional baryons relatively insignificant.

PREREQUISITES
  • Understanding of particle physics and conservation laws
  • Familiarity with proton-proton collision dynamics
  • Knowledge of baryons, pions, and kaons
  • Basic grasp of quantum chromodynamics (QCD)
NEXT STEPS
  • Research proton-proton collision experiments at CERN's Large Hadron Collider (LHC)
  • Study the role of gluons and sea quarks in high-energy collisions
  • Learn about baryon production mechanisms in particle physics
  • Examine conservation laws in particle interactions
USEFUL FOR

Particle physicists, researchers in high-energy physics, and students studying quantum mechanics and particle interactions will benefit from this discussion.

collision of two protons at about 1.8 Gev results in
p + p --> p + p + p + p*
will collision at an energy of 3.6 Gev result in
p + p --> p + p + p + p + p* + p*
if not what else happens ?

Yes, along with anything and everything that's consistent with the conservation laws, especially energy conservation, charge and baryon number. Lighter particles are more likely. So along with two or more baryons you'll get pions, kaons, gammas, lepton pairs, etc.
 
I think you would have a really hard time colliding the protons head on. Most of the time you would just be colliding the gluons (or sea quarks as well) inside the protons. Its actually really hard to get two protons to collide head on. Even if you did, I don't think the cross section for p p -> p p p p* or p p -> p p p p* p p* would be very significant... But i have not done that calculation to be honest.
