SUMMARY

The discussion focuses on the collision of antimatter and matter, specifically a positron colliding with an electron. When a positron with lower kinetic energy collides with an electron at rest, the result is the emission of two gamma rays with varying energies. This process can be analyzed using the center of momentum frame, where the gamma rays are emitted back-to-back, and then transformed to the lab frame using relativistic kinematics.

PREREQUISITES
  • Understanding of relativistic kinematics
  • Knowledge of particle physics, specifically positrons and electrons
  • Familiarity with gamma ray emission processes
  • Concept of center of momentum frame in collisions
NEXT STEPS
  • Study the principles of relativistic kinematics in detail
  • Explore the properties and behavior of gamma rays in particle collisions
  • Investigate the concept of center of momentum frame and its applications
  • Learn about the interactions between matter and antimatter
USEFUL FOR

Physicists, students of particle physics, and anyone interested in the dynamics of matter-antimatter interactions and gamma ray emissions.

Suppose an antimatter at lower energy(K.E) collides with a matter in higher energy then what will be the output.

two gamma rays with different energy..

you can always transform it to the centre of momentum frame, so a positron impinging an electron at rest in lab-frame, will result in two back-to-back gamma rays in their centre of mass frame, which you then transform back to the lab frame. Simple relativistic kinematics problem.
