A Local Monte Carlo implementation of the non-abelian Landau-Pomerantschuk-Migdal effect
(2009) In Physical Review Letters 103(15).- Abstract
- The non-Abelian Landau-Pomeranschuk-Migdal (LPM) effect arises from the quantum interference between spatially separated, inelastic radiation processes in matter. A consistent probabilistic implementation of this LPM effect is a prerequisite for extending the use of Monte Carlo (MC) event generators to the simulation of jetlike multiparticle final states in nuclear collisions. Here, we propose a local MC algorithm, which is based solely on relating the LPM effect to the probabilistic concept of formation time for virtual quanta. This accounts probabilistically for the characteristic L² dependence of average parton energy loss and the characteristic 1/√ω modification of the non-Abelian LPM effect. Additional kinematic constraints are found... (More)
