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 , motivating scenarios in which dark matter (DM) preferentially scatters at large recoil ener…
From Thermal History to Multi-Messenger Signatures in Symmetric Dark Sector
Debajyoti Choudhury, Jaydeb Das, Divya Sachdeva
We investigate a -symmetric extension of the Standard Model consisting of a right-handed neutrino (), a dark fermion () 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 in t…
Neutrino Nonstandard Interactions and Lepton Flavor Universality violation at SND@LHC via charm production
Bhubanjyoti Bhattacharya, Alakabha Datta, Elena Graverini +3
In this work, we explore the effect of neutrino nonstandard interactions (NSI) involving the charm quark at SND@LHC. Using an effective description of new physics in terms of four-…
Dark Matter spikes around Sgr A* in -rays
Shyam Balaji, Divya Sachdeva, Filippo Sala +1
We use H.E.S.S. -ray observations of Sgr A* to derive novel limits on the Dark Matter (DM) annihilation cross-section. We quantify their dependence on uncertainties i) in the DM…
Bounds on boosted dark matter from direct detection: The role of energy-dependent cross sections
Debjyoti Bardhan, Supritha Bhowmick, Diptimoy Ghosh +2
The recoil threshold of Direct Detection experiments limits the mass range of Dark Matter (DM) particles that can be detected, with most DD experiments being blind to sub-MeV DM pa…
