Prospects for relic neutrino detection using nuclear spin experiments

Yeray Garcia del Castillo, Giovanni Pierobon, Dipan Sengupta +1

Direct detection of the cosmic neutrino background (CB) remains one of the most formidable experimental challenges in modern physics. In this work, we extend recent studies of C…

Radion Portal Freeze-Out Dark-Matter

R. Sekhar Chivukula, Joshua A. Gill, Kenn S. Goh +5

We show that, in a consistent model of a stabilized extra-dimensional theory, the radion can serve as a natural portal between ordinary matter and WIMP dark matter. With an effecti…

t-channel dark matter at the LHC -- a whitepaper

Chiara Arina, Benjamin Fuks, Luca Panizzi +67

This report, summarising work achieved in the context of the LHC Dark Matter Working Group, investigates the phenomenology of -channel dark matter models, spanning minimal setup…

Limits on Kaluza-Klein Portal Dark Matter Models

R. Sekhar Chivukula, Joshua A. Gill, Kirtimaan A. Mohan +4

We revisit the phenomenology of dark-matter (DM) scenarios within radius-stabilized Randall-Sundrum models. Specifically, we consider models where the dark matter candidates are St…

Revisiting Cosmological Constraints on Supersymmetric SuperWIMPs

Meera Deshpande, Jan Hamann, Dipan Sengupta +3

SuperWIMPs are extremely weakly interacting massive particles that inherit their relic abundance from late decays of frozen-out parent particles. Within supersymmetric models, grav…
