Gravitational Waves and Cosmological Observables from First-Order Phase Transitions: Thermal Corrections at Low Temperature
Katharena Christy, James B. Dent, Sumit Ghosh +2
We consider the impact on cosmological first-order phase transitions (FOPTs) of low-temperature thermal corrections to the effective potential. These are corrections from degrees o…
Non-standard neutrino interactions mediated by a light scalar at DUNE
Bhaskar Dutta, Sumit Ghosh, Kevin J. Kelly +3
We investigate the effect on neutrino oscillations generated by beyond-the-standard-model interactions between neutrinos and matter. Specifically, we focus on scalar-mediated non-s…
Explaining ATOMKI, , and MiniBooNE anomalies with light mediators in extended model
Sumit Ghosh, Pyungwon Ko
We consider extensions of Type-I 2HDM plus a singlet scalar , introducing a new Higgs doublet and a singlet charged under . The SM Higgs doublet $…
Non-standard neutrino interactions in light mediator models at reactor experiments
Bhaskar Dutta, Sumit Ghosh, Tianjun Li +2
Compared to other neutrino sources, the huge anti-neutrino fluxes at nuclear reactor based experiments empower us to derive stronger bounds on non-standard interactions of neutrino…
Extension of Standard Model: A Sub-GeV Dark Matter Model
Bhaskar Dutta, Sumit Ghosh, Jason Kumar
We present a model based on a extension of the Standard Model. The model addresses the mass hierarchy between the third generation and the first two generation fermion…
Sensitivity to Dark Sector Scales from Gravitational Wave Signatures
James B. Dent, Bhaskar Dutta, Sumit Ghosh +2
We consider gravitational wave signals produced by a first-order phase transition in a theory with a generic renormalizable thermal effective potential of power law form. We find t…
Probing an MeV-Scale Scalar Boson in Association with a TeV-Scale Top-Quark Partner at the LHC
Bhaskar Dutta, Sumit Ghosh, Alfredo Gurrola +3
Searches for new low-mass matter and mediator particles have actively been pursued at fixed target experiments and at colliders. It is challenging at the CERN LHC, but the…
