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…

Solving Cosmological Puzzles using Finite Temperature SMEFT
Debajyoti Choudhury, Jaydeb Das, Tripurari Srivastava
We study a minimal framework that naturally yields viable Dark Matter, a strong first-order electroweak phase transition and low-scale resonant leptogenesis. Augmenting the Standar…
