Diffuse Supernova Neutrinos with Secret Neutrino Interactions
Praveen Bharadwaj, Utpal Chattopadhyay, Dilip Kumar Ghosh +1
The Diffuse Supernova Neutrino Background (DSNB), an isotropic flux arising from the cumulative neutrino emission of all stellar core-collapse events throughout cosmic history, is…
Probing lepton number violation at FCC-ee
Praveen Bharadwaj, Sanjoy Mandal, Rojalin Padhan +2
We propose high-multiplicity final-state signatures, such as with denoting , , as probes of lepton number violation (LN…
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…
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…
