标题： Bremsstrahlung neutrinos from electron-electron scattering in a relativistic degenerate electron plasma

摘要： 我们计算了由于电子-电子散射在相对论简并电子等离子体中的中微子对韧致辐射。正确处理介质中的光子传播函数，即包括纵向部分的德拜屏蔽和横向部分的朗道阻尼，所得的中微子发射率比仅施加德拜屏蔽于横向部分时高出几个数量级。我们的结果显示，这一介质内的过程能够与其它中微子辐射源竞争，在某些情况下甚至可以成为主导的中微子发射机制。我们还讨论了这种计算自然延伸到有能隙和无能隙夸克物质中的夸克-夸克韧致辐射的情况。 显示英文摘要

摘要： We present a calculation of neutrino pair bremsstrahlung due to electron-electron scattering in a relativistic degenerate plasma of electrons. Proper treatment of the in-medium photon propagator, i.e., inclusion of Debye screening of the longitudinal part and Landau damping of the transverse part, leads to a neutrino emissivity which is several orders of magnitude larger than when Debye screening is imposed for the tranverse part. Our results show that this in-medium process can compete with other sources of neutrino radiation and can, in some cases, even be the dominant neutrino emission mechanism. We also discuss the natural extension to quark-quark bremsstrahlung in gapped and ungapped quark matter.
