Fate of Metastable Vacua in the Type-II Two-Higgs Doublet Model
Debtosh Chowdhury, Kirtimaan A. Mohan, Poulami Mondal +1
The scalar potential of the Two-Higgs-Doublet Model (2HDM) can admit multiple non-degenerate vacua due to the presence of the two Higgs doublets unlike the Standard Model (SM). For…
Constraints on the inflationary vacuum and reheating era from NANOGrav
Debtosh Chowdhury, Rounak Nath, Sudipta Show
NANOGrav and various pulsar timing array experiments recently reported compelling evidence for a stochastic gravitational wave background (SGWB). Such a background may originate fr…
Addressing the Hubble tension with Sterile Neutrino Dark Matter
Debtosh Chowdhury, Md Sariful Islam
One of the promising dark matter (DM) candidates is a keV-scale sterile neutrino. In the early universe, the observed relic of the sterile neutrino DM is generated via the Dodelson…
One-loop renormalization and parameter in the Georgi-Machacek model
Debtosh Chowdhury, Anirban Kundu, Poulami Mondal +2
We study the one-loop renormalization of the Georgi-Machacek model. At one loop, the renormalization of the model is phenomenologically important when triggered by operators that a…
