中微子的发射及其向超新星激波区的能量传输对热密核物质的物理十分敏感,由于核力的强关联,这是一个复杂的问题。利用基于Skyrme有效相互作用的自洽方法,我们得到了超新星物质中电子中微子和反中微子的带电不透明度。我们包括了由于核相互作用引起的平均场能量移动和由于RPA关联引起的修正。给出了完整的Skyrme相互作用的处理,包括自旋-轨道项。为了测试RPA修正的效果,使用与许多无限物质约束一致的不同Skyrme参数来计算中微子和反中微子的不透明度。
Neutrino emission and their transport of energy to the supernova shock region are sensitive to the physics of hot and dense nuclear matter, which is a complex problem due to the strong correlations induced by nuclear forces. We derive charged-current opacities for electron neutrinos and antineutrinos in supernova matter using a self-consistent approach based on the Skyrme effective interaction. We include a mean field energy shift due to nuclear interaction and corrections due to RPA correlations. A complete treatment of the full Skyrme interaction, including a spin-orbit term, is given. To test the effect of RPA corrections, neutrino and antineutrino opacities are computed using different Skyrme parametrizations consistent with a number of infinite matter constraints.
