Majoron Dark Matter, High-Scale Seesaw, and Leptogenesis
Brian Batell, Arnab Dasgupta, Swapnil Dutta +1
We study the cosmology and observational probes of majoron dark matter in a high-scale seesaw framework with spontaneously broken lepton number. Right-handed neutrinos naturally ge…
Collider probes of baryogenesis with maximal CP asymmetry
Debasish Borah, Kun Cheng, Arnab Dasgupta +2
We propose a novel collider probe of baryogenesis at TeV scale by measuring decay asymmetries into particle and anti-particle final states. Motivated by the idea of Dirac leptogene…
Leptogenesis from Dark Matter Coannihilation
Simran Arora, Debasish Borah, Arnab Dasgupta +2
We propose a minimal extension of the type-I seesaw model to realise leptogenesis from the co-annihilation of dark sector particles. The type-I seesaw model is extended with a sing…
Reviving WIMP dark matter with temperature-dependent couplings
Debasish Borah, Arnab Dasgupta, Tong Arthur Wu
The persistent null results at dark matter (DM) direct-detection experiments have pushed the popular weakly interacting massive particle (WIMP) DM to tight corners. Generic WIMP mo…
Electromagnetic Dirac Cogenesis
Debasish Borah, Arnab Dasgupta
We propose a novel cogenesis mechanism by utilising the two-body decay of heavy vector-like fermions to dark matter (DM) and right chiral part of light Dirac neutrino via…
ALPy Cogenesis
Disha Bandyopadhyay, Debasish Borah, Arnab Dasgupta
We propose a novel cogenesis scenario by utilising the two-body decay of heavy right-handed neutrino (RHN) via an effective operator involving an axion-like particle (ALP) dark mat…
