Generalized Chiral : Towards a Less Constrained and Dark Matter

Ranjeet Kumar, Hemant Kumar Prajapati

Extensions of the Standard Model by a gauge symmetry predict a new boson, whose mass is severely constrained by high-mass dilepton resonance searches at the LHC. We…

The Simplest Dirac Scoto-Seesaw Realization

Sin Kyu Kang, Ranjeet Kumar, Hemant Kumar Prajapati

We present a simple Dirac scoto-seesaw framework based on the anomaly-free charge assignment for . This chiral charge assignment naturally accounts fo…

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…

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)_…

model in light of the CDF II result

Sanjoy Mandal, Hemant Prajapati, Rahul Srivastava

Recent CDF II collaboration's result on mass measurements contradict Standard Model prediction, requiring new physics to explain this anomaly. Such new physics may manifest thr…
