Spin light of neutrino efficiency in Gamma-Ray Bursts
Session and Location
Wednesday Session, Poster Wall #167 (Ballroom)
The spin light of neutrino (SLν) is the electromagnetic radiation emitted by a neutrino due to its magnetic moment when the particle is moving in external environments, i.e. in the presence of matter and/or electromagnetic or gravitational fields. One of the most promising astrophysical conditions for this phenomenon to be manifested in are realized in Gamma-Ray Bursts (GRB) where generation of ultra-high energy neutrinos is anticipated and the matter density can reach values on the order of the nuclear density. In the present work we discuss the possibility of the SLν radiation in GRBs during their prompt stage. We search for conditions of the best radiation efficiency within the GRB site and describe the most important radiation characteristics such as the total rate and power, the angular distribution and polarization. On this basis we analyze the possibility to find the imprint of the SLν in the observed gamma-ray flux.
