Inelastic Dark Matter from a Higher-Dimensional Operator: The LUX-ZEPLIN High-Recoil Event and Thermal Relic

Debajyoti Choudhury, Jaydeb Das, Divya Sachdeva

The recent LUX-ZEPLIN (LZ) data shows a nuclear-recoil event around $248 keV$ , motivating scenarios in which dark matter (DM) preferentially scatters at large recoil ener…

From Thermal History to Multi-Messenger Signatures in $Z_{3}$ Symmetric Dark Sector

Debajyoti Choudhury, Jaydeb Das, Divya Sachdeva

We investigate a $Z_{3}$ -symmetric extension of the Standard Model consisting of a right-handed neutrino ( $N_{R}$ ), a dark fermion ( $χ$ ) that dominates the relic density and a…

Suppressed Magnetogenesis from Ultralight Dark Matter due to Finite Conductivity

Ramkishor Sharma, Samarth Majumdar, Divya Sachdeva

Recently, a mechanism for generating astrophysically relevant magnetic fields via ultralight pseudoscalar dark matter, through the coupling term $g_{ϕ γ} ϕ F_{μν} F ~^{μν}$ in t…
