Astrophysical hints for magnetic black holes
Diptimoy Ghosh, Arun Thalapillil, Farman Ullah
We discuss a cornucopia of potential astrophysical signatures and constraints on magnetically charged black holes of various masses. As recently highlighted, being potentially viab…
Constraints on Axion-Lepton coupling from Big Bang Nucleosynthesis
Diptimoy Ghosh, Divya Sachdeva
In this article, we study the implications of the coupling between Axion-Like-Particles (ALPs) and Leptons to cosmology, in particular, the Big Bang Nucleosynthesis (BBN). We show…
Neutrino charge constraints from scattering to the weak gravity conjecture to neutron stars
Arindam Das, Diptimoy Ghosh, Carlo Giunti +1
In various extensions of the Standard Model of particle physics, and intriguingly even in the three-generation Standard Model without neutrino masses, neutrinos are allowed to have…
B-meson charged current anomalies: the post-Moriond status
Debjyoti Bardhan, Diptimoy Ghosh
In this note, we discuss the impact of the recent Belle result on the various theoretical explanations of the and anomalies. The pure tensor explanation, which was…
Combined explanations of B-physics anomalies: the sterile neutrino solution
Aleksandr Azatov, Daniele Barducci, Diptimoy Ghosh +2
In this paper we provide a combined explanation of charged- and neutral-current -physics anomalies assuming the presence of a light sterile neutrino which contributes to t…
Anatomy of anomalies
Aleksandr Azatov, Debjyoti Bardhan, Diptimoy Ghosh +2
In recent times, one of the strongest hints of Physics Beyond the Standard Model (BSM) has been the anomaly in the ratios and measured in the charged current dec…
