CassiopeiaA said:Why do particles scatter in particle-particle collision while photons don't in photon-photon collisions,
Photon-photon scattering is a process in which two photons interact with each other, resulting in the creation of new particles. This phenomenon is predicted by quantum field theory and has been observed in high-energy particle collisions.
Photon-photon scattering can occur when two photons come close enough to each other that they can interact through the electromagnetic force. This interaction leads to the creation of an electron-positron pair or other particles depending on the energy of the photons.
Photon-photon scattering is significant because it provides insights into the fundamental interactions of particles and the nature of the universe. It also has important applications in understanding high-energy processes, such as those that occur in particle accelerators.
No, photon-photon scattering is a rare phenomenon that requires extremely high-energy photons to occur. These conditions are not present in everyday life, so photon-photon scattering is not observable in our daily experiences.
Some current research areas related to photon-photon scattering include studying the properties of the Higgs boson and searching for new particles in high-energy experiments. Scientists are also investigating the potential of using photon-photon scattering as a tool for understanding dark matter and the early universe.
