Probing the Inert Doublet Dark Matter with Stellar-Mass Black Hole Mini-Spikes
Rameswar Sahu
The nature of dark matter remains a central unresolved problem in contemporary physics, motivating the exploration of well-defined extensions of the Standard Model. Among these, th…
Scrutinizing Fermionic Dark Matter in Scotogenic Model with Low Reheating Temperature
Abhishek Roy, Rameswar Sahu
The scotogenic model provides a minimal and elegant framework that simultaneously explains neutrino masses and accommodates a viable dark matter (DM) candidate. In this work, we in…
Resurrecting Kaluza-Klein Dark Matter with Low-Temperature Reheating
Kirtiman Ghosh, Abhishek Roy, Rameswar Sahu
In Universal Extra Dimension (UED) scenarios, the lightest Kaluza-Klein (KK) particle is naturally stable due to a remnant discrete symmetry, KK parity, arising from extra-dimensio…
Integrating Physics Inspired Features with Graph Convolution
Rameswar Sahu
With the advent of advanced machine learning techniques, boosted object tagging has witnessed significant progress. In this article, we take this field further by introducing novel…
A Comprehensive Search for Leptoquarks Decaying into Top- Final States at the Future LHC
Debabrata Sahoo, Rameswar Sahu, Kirtiman Ghosh
We studied the collider phenomenology of third-generation scalar leptoquarks at the Large Hadron Collider (LHC) with a 14 TeV center-of-mass energy. The analysis focuses on leptoqu…
Advancing Higgsino Searches by Integrating ML for Boosted Object Tagging and Event Selection
Rameswar Sahu, Debabrata Sahoo, Kirtiman Ghosh
Higgsinos near the TeV mass range are highly motivated as they offer an elegant solution to the naturalness problem in the Standard Model. Extensive searches for such higgsinos wit…
