Return of the CHAMPs: A clockwork portal to charged dark matter
Debajyoti Choudhury, Vineet K. Jha, Suvam Maharana
The paper proposes a model in which dark matter carries a small electric charge (a CHAMP) using the clockwork mechanism, showing that it can satisfy relic density and experimental…
Polarisation fractions in : U-Spin constraints and new physics signatures
Debajyoti Choudhury, Suman Kumbhakar, Anirban Kundu +1
We investigate the decays of mesons, {\em i.e.}, , , , and their antiparticles, to two light vector mesons (). We use the SU(2) U-spin symmetry, wh…
Dark photon -- Assisted Primordial Magnetogenesis
Debottam Nandi, Debajyoti Choudhury
Magnetic fields observed across cosmic scales are difficult to explain within conventional physics. A primordial origin is, thus, often assumed. While a nonminimal coupling of the…
Axion Icebergs: Clockwork ALPs at hadron colliders
Srimoy Bhattacharya, Debajyoti Choudhury, Suvam Maharana +1
Scenarios with multiple pseudoscalars are interesting as they usually tend to provide a framework to naturally realize a light axion with a large decay constant which has rich appl…
