Explaining , the KOTO anomaly and the MiniBooNE excess in an extended Higgs model with sterile neutrinos
Bhaskar Dutta, Sumit Ghosh, Tianjun Li
We consider a simple extension of the Standard Model (SM) by a complex scalar doublet and a singlet along with three sterile neutrinos. The sterile neutrinos mix with the SM neutri…
Contributions to from the dark photon of
Bhaskar Dutta, Sumit Ghosh, Jason Kumar
We consider the effect on early Universe cosmology of the dark photon associated with the gauging of , a symmetry group under which only right-handed Standard Model fer…
Induced Spin-texture at 3 Transition Metal/Topological Insulator Interfaces
Slimane Laref, Sumit Ghosh, Evgeny Y. Tsymbal +1
While some of the most elegant applications of topological insulators, such as quantum anomalous Hall effect, require the preservation of Dirac surface states in the presence of ti…
and the ANITA anomalous events in a three-loop neutrino mass model
Mohammad Abdullah, Bhaskar Dutta, Sumit Ghosh +1
The most recent measurement of the fine structure constant leads to a 2.4 deviation in the electron anomalous magnetic moment -2, while the muon anomalous magnetic momen…
A sub-GeV dark matter model
Bhaskar Dutta, Sumit Ghosh, Jason Kumar
We propose an extension of the Standard Model gauge symmetry by the gauge group in order to address the Yukawa coupling hierarchy between the third generation fermions…
Non-equilibrium spin density and spin-orbit torque in three dimensional topological insulators - antiferromagnet heterostructure
Sumit Ghosh, Aurelien Manchon
We study the behavior of non-equilibrium spin density and spin-orbit torque in a topological insulator - antiferromagnet heterostructure. Unlike ferromagnetic heterostructures wher…
