Transition rate for a process involving particles with high momentum in a plasma and infrared physics for a QED plasma
- Department of Physics, Purdue University, West Lafayette, Indiana 47907 (United States)
We derive a formula for computing the transition rate for a process involving particles with momentum much higher than the temperature and chemical potentials in a plasma by using an effective field theory approach. We apply it to the collision of charged particles with hard momentum inside a QED plasma. The Debye screening effect and the damping of a charged particle moving in a QED plasma are studied. Using Bloch-Nordsieck resummation, the infrared divergences due to the absence of magnetic screening for the QED plasma are shown not to appear in physically measurable rates. The soft plasmon absorption and emission for charged particles are discussed. {copyright} {ital 1996 The American Physical Society.}
