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 +1

We propose high-multiplicity final-state signatures, such as $e^{+} e^{-} \to N N \to ℓ^{+} ℓ^{+} 4 j$ with $ℓ$ denoting $e, μ$ , $τ$ , as probes of lepton number violation (LN…

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 ( $10 - 1000$ ) GeV mass range…
