We present a singly charged scalar extension of the scotogenic model, the scotogenic-Zee
model, which resolves the recently reported deviations in the W boson mass as well as …

The presence of any extra radiation energy density at the time of cosmic microwave
background formation can significantly impact the measurement of the effective relativistic …

A bstract Stringent constraints on the interactions of dark matter with the Standard Model
suggest that dark matter does not take part in gauge interactions. In this regard, the …

A bstract We study ultra-violet completions for d= 6 four-fermion operators in the standard
model effective field theory (SMEFT), focusing on models that contain cold dark matter …

The CDF-II collaboration's recent high-precision measurement of W-boson mass indicates
new physics contribution (s) beyond the Standard Model. We investigate the possibility of …

A bstract The neutrino mass and dark matter (DM) problems are addressed in a Standard
Model extension where the type-II seesaw and scotogenic mechanisms coexist. The model …

A bstract We propose simple scoto-seesaw models to account for dark matter and neutrino
masses with spontaneous CP violation. This is achieved with a single horizontal\({\mathcal …

A bstract We study the case of a pseudo-scalar dark matter candidate which emerges from a
complex scalar singlet, charged under a global U (1) symmetry, which is broken both …

A bstract Recently, an increasing interest in UV/IR mixing phenomena has drawn attention to
the range of validity of standard quantum field theory. Here we explore the consequences of …

We study the possibility of probing the radiative Dirac seesaw model with dark sector
particles going inside the loop, popularly referred to as the Dirac scotogenic model via …
