*Title*: Dodelson-Widrow Mechanism In the Presence of Self-Interacting
Neutrinos
*Speaker*: Dr. Manibrata Sen (UC Berkeley and Northwestern U.)
*Abstract*: keV-scale gauge-singlet fermions, allowed to mix with the
active neutrinos, are elegant dark matter (DM) candidates. They are
produced in the early universe via the Dodelson-Widrow mechanism and can be
detected as they decay very slowly, emitting X-rays. In the absence of new
physics, this hypothesis is virtually ruled out by astrophysical
observations. Here, we show that new interactions among the active
neutrinos allow these sterile neutrinos to make up all the DM while safely
evading all current experimental bounds. The existence of these new
neutrino interactions may manifest itself in next-generation experiments,
including DUNE.
We are looking forward to seeing you.
Best regards,
Dong Woo Kang
