Parameterizations of the Hubble Constant from the Binned Type Ia Supernova Master Sample: Logarithmic versus Power-law Forms
Maria Giovanna Dainotti, Avik Banerjee, Andre' LeClair +1
Motivated by the Hubble tension and the increasing debate about the redshift-dependency in the inferred Hubble constant, we investigate its dependence within the flat CDM framew…

Light Vector Dark Matter via a Magnetic Dipole Portal: Bridging Direct Detection and Fixed-Target Searches
Avik Banerjee, Riccardo Catena, Taylor R. Gray
We present a model featuring sub-GeV vector dark matter by augmenting the Standard Model with a new non-Abelian dark , spontaneously broken by the vacuum expectation value…

Drell-Yan constraints on charged scalars: a weak isospin perspective
Avik Banerjee, Dipankar Das, Samadrita Mukherjee +1
Charged scalars appear in many motivated extensions beyond the Standard Model. We analyze the constraints on charged scalar pair production via the Drell-Yan process at the Large H…
