Jets in QCD media: From color coherence to decoherence
(2012) In Physics Letters. Section B: Nuclear, Elementary Particle and High-Energy Physics 707(1). p.156-159- Abstract
- We investigate soft gluon radiation off a quark-antiquark antenna in both color singlet and octet configurations traversing a dense medium. We demonstrate that, in both cases, multiple scatterings lead to a gradual decoherence of the antenna radiation as a function of the medium density. In particular, in the limit of a completely opaque medium, total decoherence is obtained, i.e., the quark and the antiquark radiate as independent emitters in vacuum, thus losing memory of their origin.
