Collisions in a particle accelerator involving some elementary particles

Click For Summary
SUMMARY

In high-energy collisions within a particle accelerator, such as those involving electrons and protons or neutrons, the interactions result in the production of various elementary particles. When an electron collides with a proton, it interacts with individual partons (quarks or gluons) rather than the proton as a whole. This leads to a chaotic outcome, generating numerous particles including pions, partons, photons, and W and Z bosons, which subsequently decay into muons. The energy level of the collision significantly influences the variety and proportions of the resulting particle fragments.

PREREQUISITES
  • Understanding of particle physics concepts, specifically elementary particles.
  • Familiarity with particle accelerators and their operational principles.
  • Knowledge of high-energy collision dynamics and quantum chromodynamics (QCD).
  • Basic comprehension of particle decay processes and particle interactions.
NEXT STEPS
  • Research the role of partons in high-energy collisions in particle physics.
  • Study the decay processes of W and Z bosons and their significance in particle interactions.
  • Explore the principles of quantum chromodynamics (QCD) and its implications for particle collisions.
  • Learn about the experimental setups and technologies used in modern particle accelerators.
USEFUL FOR

Physicists, particle accelerator engineers, and students of particle physics seeking to understand the complexities of high-energy collisions and the resulting particle interactions.

What would happen if an electron were accelerated in an attempt to collide with an accelerated proton in a particle accelerator?

What would happen in a collision between an electron and a neutron?

Everything. At sufficiently high energy it hardly matters what the original particles were, you'll get all possible fragments in any case, although in different proportions. At high energy the electron won't collide with the proton or neutron as a whole anyway, rather it collides with one of the individual partons (quark or gluon). From then on you'll get the usual chaos: zillions of pions, more partons (which decay into jets), photons, Ws and Zs (which decay into muons)...
