Proton-proton Collision at High Energies

Abstract

The presented work effective section of neutralino birth calculated for proton-proton collision at high energies. Proton-proton collision is considered in parton model and Feynman diagram was used in calculations. One of possible process: a process with γ photon formation was considered. It is shown that an effective section of process with unpolarized and polarized protons is different. The ratio of effective sections of process with unpolarized and polarized protons is 1-λ1λ2. The energy spectrum of neutralino born has been studied. The spectrum has an asymmetric shape and is shallow towards lower energies. The maximum value of the spectrum increases exponentially as the energy of proton collision increases.
