Twilight of the WIMP: Comprehensive Phenomenology of Electroweak Triplet Dark Matter
Gaurav, Niharika Shrivastava, Rahul Srivastava +1
We present a comprehensive study of dark matter phenomenology in standard model extensions featuring an electroweak triplet scalar or fermion with hypercharge or . T…
Dark Matter Induced Proton Decays
Ranjeet Kumar, Rahul Srivastava
We propose a novel theoretical framework in which proton decay is induced by the dark matter. While proton decay requires violation of the symmetry, dark matter stability oft…
Light and Heavy from Flavored Chiral Gauge Symmetries: Purely Axial and Mixed Vector-Axial Couplings
Hemant Kumar Prajapati, Rahul Srivastava
Model independent phenomenological studies, ranging from neutrino to B-physics, often consider effective interactions involving either purely vector (V), purely axial vector (A), o…
Zooming in on `bi-large' neutrino mixing with the first JUNO results
Gui-Jun Ding, Ranjeet Kumar, Newton Nath +2
The leptonic mixing matrix is examined within bi-large mixing patterns and confronted with the latest results announced by the Jiangmen Underground Neutrino Observatory (JUNO). We…
Flavor Imprints on Novel Low Mass Dark Matter
Ranjeet Kumar, Hemant Kumar Prajapati, Rahul Srivastava +1
We present a Majorana scotogenic-like loop framework in which neutrino mass generation and dark matter stability are intrinsically connected to the breaking of the discrete flavor…
Type-III Scotogenic Model: Inflation, Dark Matter and Collider Phenomenology
Labh Singh, Rahul Srivastava, Surender Verma +1
We investigate an extension of the Type-III scotogenic model by incorporating a real singlet scalar. This scalar plays a crucial role as the inflaton due to its non-minimal couplin…
