Exothermic dark-photon dark matter and the LZ high-recoil event: finite-reheating constraints
Kuldeep Deka
An excited dark-matter state can produce a high-energy nuclear recoil by releasing its mass splitting in a collision. Motivated by the ~keV LUX--ZEPLIN candidate, we study fre…
Reheating the FCC: Probing Early Matter Domination with Long-Lived Particles
Nicolás Bernal, Giovanna Cottin, Kuldeep Deka +1
We study a GeV-scale Higgs-portal scalar that can dominate the early Universe and later decay into Standard Model states, ending an early matter-dominated era. Ordinary cosmic…
Freeze-in and ultra-relativistic freeze-out during general reheating scenarios
Kuldeep Deka
The dark-matter relic abundance can depend sensitively on the thermal history before radiation domination. We derive a general analytic framework for dark-matter production from th…
Sterile neutrino Dark Matter in the minimal Dirac Seesaw
J. Adhikary, A. Batra, K. Deka +1
We study sterile neutrino dark matter in a minimal Type-I Dirac seesaw framework where the states responsible for generating Dirac neutrino masses at tree level can be viable dark…
Chasing the muon EDM to constrain the SMEFT and UV models
Kuldeep Deka, Marta Losada, Yosef Nir
Following a proposal for an experiment with sensitivity to an electric dipole moment (EDM) of the muon of order cm, three to four orders of magnitude bel…
Freezing-in Cannibals with Low-reheating Temperature
Nicolás Bernal, Esau Cervantes, Kuldeep Deka +1
The freeze-in mechanism provides a compelling framework for dark matter (DM) production, particularly suited to scenarios involving feeble interactions with the Standard Model (SM)…
