Flavor specific chiral framework for explaining the ATOMKI anomaly
Aditya Batra, F. R. Joaquim, Hemant Prajapati +1
Recent anomalies in nuclear transitions observed by the ATOMKI Collaboration suggest the existence of a new boson with a mass of MeV. A theoretically consistent interpret…
Primordial black holes as cosmic accelerators of light dark matter: Novel direct detection constraints
Sk Jeesun, Anirban Majumdar, Rahul Srivastava
Current multi-tonne-scale dark matter (DM) detectors are largely incapable of detecting light dark matter from the Galactic halo due to the energy threshold limitations of their re…
Cosmic-ray-electron boosted light dark matter: Implications of LZ 2025 data
Sk Jeesun, Anirban Majumdar
Current multiton detectors put stringent constraints on the GeV-scale galactic dark matter, pushing the allowed cross section almost toward the neutrino fog, yet remain mostly inse…
Minimal A4 Type-II Seesaw Realization of Testable Neutrino Mass Sum Rules
Salvador Centelles Chuliá, Ranjeet Kumar
We propose a flavour model based on an symmetry combined with a type-II seesaw mechanism for neutrino mass generation. The resulting neutrino mass matrix obeys a sum rule tha…
New light mediators and the neutrino fog: Implications from XENONnT nuclear recoil data
Valentina De Romeri, Anirban Majumdar, Dimitrios K. Papoulias +1
Current ton-scale, xenon-based dark matter (DM) direct detection experiments have now reached the sensitivity required to observe solar neutrinos, marking the onset of the so-calle…
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…
Limits on the axion-photon coupling from Chandrayaan-2 observations
Tanmoy Kumar, N. P. S. Mithun, Subhendra Mohanty +3
Axions and axion-like particles (ALPs) have gained immense attention in searches for beyond Standard Model (BSM) physics. Experiments searching for axions leverage their predicted…
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…
Axion framework with color-mediated Dirac neutrino masses
A. Batra, H. B. Câmara, F. R. Joaquim +3
We propose a KSVZ-type axion framework in which vector-like quarks (VLQ) and colored scalars generate Dirac neutrino masses radiatively. The global Peccei-Quinn symmetry (under whi…

We explore the potential of reactor antineutrino-induced Coherent Elastic Neutrino-Nucleus Scattering (CENS) data from the CONUS+ experiment to investigate both the Standard Mod…
Constraining low scale dark hypercharge symmetry at spallation, reactor and Dark Matter direct detection experiments
Anirban Majumdar, Dimitrios K. Papoulias, Hemant Prajapati +1
Coherent elastic neutrino-nucleus (CENS) and elastic neutrino-electron scattering (EES) data are exploited to constrain ``chiral'' gauged models with light vector…
Dark hyperCharge Symmetry
Hemant Prajapati, Rahul Srivastava
We introduce a new class of symmetries where all Standard Model fermions are ``chiral," i.e., the left- and right-handed components have different charges under the $U(1)_…
Energy-scaling behavior of intrinsic transverse momentum parameters in Drell-Yan simulation
CMS Collaboration
An analysis is presented based on models of the intrinsic transverse momentum (intrinsic ) of partons in nucleons by studying the dilepton transverse momentum in Drel…
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…
