High-Quality Axion Dark Matter at Gravitational Wave Interferometers
Disha Bandyopadhyay, Debasish Borah, Nayan Das +1
Gravitational effects are known to violate global symmetries, threatening the Peccei-Quinn (PQ) solution to the strong CP problem. Ultraviolet completions featuring a gauged …
Multi-messenger FIMP
Debasish Borah, Nayan Das, Sahabub Jahedi +1
We propose a multi-messenger frontier probe of non-thermal or freeze-in massive particle (FIMP) dark matter (DM) by considering an effective field theory (EFT) setup. Assuming lept…
Possible origin of the KM3-230213A neutrino event from dark matter decay
Debasish Borah, Nayan Das, Nobuchika Okada +1
We study the possibility of the highest energy neutrino event with 220 PeV energy, detected recently by the KM3NeT experiment to be originating from heavy dark matter (DM) decay. C…
Axion misalignment with memory-burdened PBH
Disha Bandyopadhyay, Debasish Borah, Nayan Das
We study the possibility of producing axion dark matter (DM) via misalignment mechanisms in a non-standard cosmological era dominated by ultra-light primordial black holes (PBH). W…
