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 f…
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…
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)_…
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…
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…
