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…
Decay: Smoking Gun Signature of Wrong-Sign Coupling
Aditya Batra, Sanjoy Mandal, Rahul Srivastava
We perform a model-independent study of new physics effects in the Higgs decay , focusing on scenarios that spoil the accidental cancellation between the direct and ind…
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…
Large lepton number violation at colliders: predictions from the minimal linear seesaw mechanism
Aditya Batra, Praveen Bharadwaj, Sanjoy Mandal +2
Small neutrino masses can be sourced by a tiny vacuum expectation value of a leptophilic Higgs doublet, and mediated by Quasi-Dirac heavy neutrinos. In such simplest linear seesaw…
