Description
Neutrino–antineutrino pair production is a key process contributing to energy loss in stars. While previous studies have examined pair creation via the collision of two (γγ→ννˉ) or three (γγγ→ννˉ) real photons, as well as photon collisions in the presence of nuclear Coulomb fields or external magnetic fields, this talk explores a new scenario.
We investigate the pair production of neutrinos and antineutrinos from a low-energy photon in the presence of a combined homogeneous magnetic field and the Coulomb field of a nucleus with charge Z.
