Why do proton and anti-proton annihilation can produce extra pions, in addition to the photons; whereas the electron and positron interaction only gives photons?
Proton and anti-proton annihilation is a process in which a proton and its antiparticle, the anti-proton, collide and are converted into energy. This process is most commonly studied in particle physics experiments.
During the annihilation process, the energy from the collision is converted into new particles, including pions. This is due to the conservation of energy and mass, as the total energy and mass of the initial particles must be equal to the total energy and mass of the resulting particles.
Pions are subatomic particles that belong to a family of particles called mesons. They are made up of a quark and an anti-quark and are important in this process because they are one of the main particles produced during proton and anti-proton annihilation.
Studying proton and anti-proton annihilation can provide valuable insights into the fundamental forces and particles of the universe. It can also help in developing new technologies, such as particle accelerators and medical imaging techniques.
No, there are no known risks associated with proton and anti-proton annihilation. This process occurs naturally in high-energy cosmic rays and has been studied extensively in controlled experiments without any harmful effects.
