SUMMARY

Proton-antiproton annihilation at rest releases 1.88 GeV of energy, as confirmed by Fermilab resources. In contrast, annihilation occurring at 2 GeV kinetic energy results in significantly higher energy release, approximately 6 GeV in the center of momentum system. This increase in energy correlates with the production of more photons during the annihilation process, demonstrating the relationship between kinetic energy and energy release in particle physics.

PREREQUISITES
  • Understanding of particle physics concepts, specifically proton-antiproton interactions.
  • Familiarity with energy conservation principles in high-energy physics.
  • Knowledge of the center of momentum frame in particle collisions.
  • Basic comprehension of photon production in particle annihilation events.
NEXT STEPS
  • Research the principles of proton-antiproton annihilation and its energy dynamics.
  • Study the concept of the center of momentum frame in particle physics.
  • Explore the relationship between kinetic energy and photon production in high-energy collisions.
  • Investigate Fermilab's resources on particle interactions and energy release mechanisms.
USEFUL FOR

Students and researchers in particle physics, physicists studying high-energy collisions, and anyone interested in the mechanics of particle annihilation and energy release.

Simple energy release question...

I've recently checked out a fermilab link which says proton-antiproton annihilation at rest releases only 1.88 GeV energy, but compare this to annihilation at 2 GeV, it releases far far more energy and also "MORE PHOTONS"...WHY?

They mean that the p and anti=p each have 2GeV kinetic energy, so the total energy in the center of momentum system is about 6 GeV.
