The LPM effect in QCD revisited

Content

The QCD analog of the Laudau-Pomeranchuk-Migdal (LPM) effect is at the core jet quenching physics. In QCD, the medium-induced gluon radiation spectrum is suppressed in the ultraviolet due to the fact that during the quantum mechanical radiation time, that increases with the gluon frequency, multiple scattering centers act coherently as a single scattering center thus reducing the radiation intensity. I will present a novel analytic approach to the problem that encompasses the two known limits: multiple-soft scattering and single-hard scattering approximations. Implications to heavy ion phenomenology will be discussed.
