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…
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…
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…
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…
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…
Dirac Scoto Inverse-Seesaw from Flavor Symmetry
Ranjeet Kumar, Newton Nath, Rahul Srivastava +1
We present a Dirac scotogenic-like one loop radiative model where the stability of dark matter is intricately linked to the breaking of flavor symmetry. This breaking induces…
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…
Dark Matter Escaping Direct Detection Runs into Higgs Mass Hierarchy Problem
Praveen Bharadwaj, Ranjeet Kumar, Hemant Kumar Prajapati +2
The current generation of Dark Matter Direct Detection Experiments has ruled out a large region of parameter space for dark matter, particularly in the () GeV mass range…
Comprehensive Phenomenology of the Dirac Scotogenic Model: Novel Low Mass Dark Matter
Salvador Centelles Chuliá, Rahul Srivastava, Sushant Yadav
The Dirac Scotogenic model provides an elegant mechanism for generating small Dirac neutrino masses at the one-loop level. A single abelian discrete symmetry simultaneously…
Cutting the Scotogenic loop: Adding flavor to Dark Matter
Ranjeet Kumar, Newton Nath, Rahul Srivastava
We introduce a framework for hybrid neutrino mass generation, wherein scotogenic dark sector particles, including dark matter, are charged non-trivially under the flavor symm…
Predictions from scoto-seesaw with modular symmetry
Ranjeet Kumar, Priya Mishra, Mitesh Kumar Behera +2
This paper's novelty lies in introducing a hybrid scoto-seesaw model rooted in discrete modular symmetry leading to several interesting phenomenological implications. The sco…
