Neutrino propagation in a weakly magnetized medium

Abstract

Abstract. Neutrino-photon processes, forbidden in vacuum, can take place in the presence of a thermal medium and/or an external electro-magnetic field, mediated by the corresponding charged leptons (real or virtual). Such interactions affect the propagation of neutrinos through a magnetized plasma. We investigate the neutrino-photon absorptive processes, at the one-loop level, for massless neutrinos in a weakly magnetized plasma. We find that there is no correction to the absorptive part of the axial-vector-vector amplitude due to the presence of a magnetic field to the linear order in the field strength.

Under-Graduate Research in Physics : An Indian Perspective

“…To be sure, a fraction of these requests arise out of genuine motivation. Sometimes, a student who have earlier worked with a particular mentor (through another form of UGR) returns to complete the work, resulting in a publication (for example, see (7)). Research institutes usually provide infrastructural support and funding for these if a faculty member agrees to mentor a student.…”
