Jet quenching in high energy heavy ion collisions by QCD synchrotronlike radiation

TLDR
In this paper, a novel mechanism for jet quenching in heavy ion collisions was proposed, whereby high-p + t partons get depleted through strong (classical) color fields.Abstract:
We consider synchrotronlike radiation in QCD by generalizing Schwinger's treatment of quantum synchrotron radiation in QED to the case of a constant chromomagnetic field. We suggest a novel mechanism for jet quenching in heavy ion collisions, whereby high-${p}_{t}$ partons get depleted through strong (classical) color fields. The latter are encountered in the color glass condensate or in the form of expanding shells of exploding sphalerons. Unlike bremsstrahlung radiation through multiple soft rescattering, synchrotron radiation converts a jet into a wide shower of soft gluons. We estimate the energy loss through this mechanism and suggest that it contributes significantly to the unexpectedly strong jet quenching observed at BNL RHIC.read more

Particle production in strong electromagnetic fields in relativistic heavy-ion collisions
TL;DR: In this paper, the authors review the origin and properties of electromagnetic fields produced in heavy ion collisions and demonstrate by explicit analytical calculation that after dropping by about one-two orders of magnitude during the first fm/c of plasma expansion, it freezes out and lasts for as long as quark-gluon plasma exists.
