Description
We present a search for low-energy electron antineutrino emission from Galactic X-ray binaries (XRBs) using data from KamLAND. XRBs are binary systems in which a black hole or neutron star accretes matter from a stellar companion. Neutrino emission in the energy range from 1.8 to 200 MeV is predicted from hadronic processes in the accretion disk and relativistic jets. XRB light-curve data from 2002 to 2023 were obtained from the Swift/BAT and MAXI missions. We examine temporal correlations between KamLAND inverse neutrino event candidates and X-ray flaring periods and place constraints on the associated neutrino emission.
