SUMMARY

Physicists at CERN successfully created anti-hydrogen through the process of pair production, which involves high-energy gamma rays interacting with atomic nuclei. This interaction results in the creation of positrons and anti-protons. Specifically, positrons are generated when gamma rays collide with the nucleus of certain atoms, leading to the production of particle-antiparticle pairs. The discussion clarifies that the creation of these particles is not random but rather a result of specific high-energy collisions.

PREREQUISITES
  • Understanding of pair production in particle physics
  • Knowledge of high-energy gamma rays and their interactions
  • Familiarity with atomic nuclei structure
  • Basic principles of particle-antiparticle creation
NEXT STEPS
  • Research the mechanisms of pair production in detail
  • Explore the role of high-energy gamma rays in particle physics
  • Study the properties and behavior of anti-protons
  • Investigate CERN's experiments related to anti-hydrogen creation
USEFUL FOR

Physicists, students of particle physics, and anyone interested in the creation and properties of antimatter will benefit from this discussion.

I just read that physicists at CERN created anti-hydrogen, and I'm wondering how exactly do you create positrons or anti-protons do you collide something and then somehow pick the mass and charge of the positron or is it created by itself? same for anti-protons?

You can create positrons by shooting high energy gamma rays into the nucleus of some atoms and it can cause pair production. Not sure if this is how they did it though.
