Energy losses of positive and negative charged particles in electron gas

Abstract

A heavy charged particle propagation through electron gas has been studied using combination of non-relativistic quantum mechanics and the Green’s functions method. The energy loss of a charged particle has been found in the case of large transferred momentum taking into account the interference term in the expression for the rate. The dependence of the energy loss of a charged particles in electron gas with nonzero temperature on the sign of the charge has been obtained.

Electron-Positron Pair Photoproduction in a Strong Magnetic Field Through the Polarization Cascade

“…In particular, the process of photon splitting (three external photon lines) in a magnetic field was studied in work [11]. Analogous diagrams are also used to explain the difference between the energy losses by protons and antiprotons [43], to describe the Barkas effect, and in chromodynamics (the effective vertex) [44]. In this work, the third-order process of − + pair photoproduction in a strong magnetic field through the polarization loop will be considered.…”
