Towards a unified description of the electroweak nuclear response

Abstract

We briefly review the growing efforts to set up a unified framework for the description of neutrino interactions with atomic nuclei and nuclear matter, applicable in the broad kinematical region corresponding to neutrino energies ranging between few MeV and few GeV. The emerging picture suggests that the formalism of nuclear many-body theory can be exploited to obtain the neutrino-nucleus cross sections needed for both the interpretation of oscillation signals and simulation of neutrino transport in compact stars.
