Photon proton interaction

Two-photon physics, also called gamma–gamma physics, is a branch of particle physics that describes the interactions between two photons. Normally, beams of light pass through each other unperturbed. Inside an optical material, and if the intensity of the beams is high enough, the beams may affect each other through a variety of non-linear effects. In pure vacuum, some weak scattering of light b… http://hst-archive.web.cern.ch/archiv/HST2002/feynman/examples.htm

WebThe photon structure function, in quantum field theory, describes the quark content of the photon.While the photon is a massless boson, through certain processes its energy can be converted into the mass of massive fermions.The function is defined by the process e + γ → e + hadrons. It is uniquely characterized by the linear increase in the logarithm of the … WebPair production is the creation of a subatomic particle and its antiparticle from a neutral boson.Examples include creating an electron and a positron, a muon and an antimuon, or a proton and an antiproton.Pair production often refers specifically to a photon creating an electron–positron pair near a nucleus. As energy must be conserved, for pair production … WebMay 18, 2024 · Assuming the CMB is at 2.7 K, if a proton interacts with it, what would be the particles resulting of this collision? I read that at the GZK cut-off (~$10^{21}$ eV), there is photo-pion production, but if the proton has three quarks, how does it produce a pion with two? Does anybody know what would it be the Feynman diagram of the process? crystal hotel bc
