Resonant axion and dark photon production in magnetic white dwarfs
Nirmalya Brahma, Ella Iles, Hugo Schérer +1
Using magnetic white dwarfs as a case study, we show that the emission of sub-MeV bosons from stellar plasmas can be substantially modified in the presence of a magnetic field. In…
Photon conversion to axions and dark photons in magnetized plasmas: a finite-temperature field theory approach
Nirmalya Brahma, Katelin Schutz
Some of the most stringent constraints on physics beyond the Standard Model (BSM) arise from considerations of particle emission from astrophysical plasmas. However, many studies a…
Photon-Dark Photon Conversion with Multiple Level Crossings
Nirmalya Brahma, Asher Berlin, Katelin Schutz
Dark photons can oscillate into Standard Model (SM) photons via kinetic mixing. The conversion probability depends sensitively on properties of the ambient background, such as the…
Resonant Pseudo-Dirac Dark Matter as a Sub-GeV Thermal Target
Nirmalya Brahma, Saniya Heeba, Katelin Schutz
Dark matter (DM) could be a pseudo-Dirac thermal relic with a small mass splitting that is coupled off-diagonally to a kinetically mixed dark photon. This model, particularly in th…
