Neutral weak currents in nucleon superfluid Fermi liquids: Larkin-Migdal and Leggett approaches
arXiv:1003.2741 · doi:10.1103/PhysRevC.81.065801
Abstract
Neutrino emission in processes of breaking and formation of nucleon Cooper pairs is calculated in the framework of the Larkin-Migdal and the Leggett approaches to the description of superfluid Fermi liquids at finite temperatures. We explain peculiarities of both approaches and explicitly demonstrate that they lead to the same expression for the emissivity in pair breaking and formation processes.
