Probing Fermion-Portal Scalar Dark Matter through Charged Vector-Like Fermions at Future Muon Colliders

Songshaptak De, Tapoja Jha, Najimuddin Khan +1

We revisit a minimal fermion-portal scalar dark matter model consisting of a real singlet scalar dark matter candidate and additional vector-like singlet and doublet charged fermio…

Inert dark matter in three Higgs doublet model: a blind spot narrative

Amit Dutta Banik, Tapoja Jha, Eija Tanskanen

We explore the phenomenology of three Higgs doublet scenario, where the scalar potential is augmented by symmetry making one doublet inert. T…

Vector Dark Matter with Higgs Portal in Type II Seesaw framework

Nandini Das, Tapoja Jha, Dibyendu Nanda

We study the phenomenology of a vector dark matter (VDM) in a gauged extension of the Standard Model (SM) which is connected to the type II seesaw framework via the Higgs…

Searching for exotic Higgs bosons from top quark decays at the HL-LHC

Gautam Bhattacharyya, Indrani Chakraborty, Dilip Kumar Ghosh +2

Exotic spin- states with unusual couplings with the gauge and matter fields of the Standard Model are worth exploring at the CERN LHC. Though our approach is largely model indep…

Zooming in on eV-MeV Scale Sterile Neutrinos in light of Neutrinoless Double Beta Decay

Tapoja Jha, Sarif Khan, Manimala Mitra +1

The existence of light sterile neutrinos, as predicted in several models, can help to explain a number of observations starting from dark mater to recent anomalies in short baselin…

Leptogenesis in an extended seesaw model with symmetry

Ujjal Kumar Dey, Tapoja Jha, Ananya Mukherjee +1

We have explored an extended seesaw model accommodating a keV sterile neutrino adopting symmetry. This model provides a natural platform for achieving resonant leptoge…

Minimal and non-minimal Universal Extra Dimension models in the light of LHC data at 13 TeV

Avnish, Kirtiman Ghosh, Tapoja Jha +1

Universal Extra Dimension (UED) is a well-motivated and well-studied scenario. One of the main motivations is the presence of a dark matter (DM) candidate namely, the lightest leve…

and in Universal Extra Dimensional Models

Cheng-Wei Chiang, Ujjal Kumar Dey, Tapoja Jha

In this work we perform a complete one-loop calculation of the flavor-changing top quark decays and in the universal extra dimensional models. We find that the…

Status of Flavour Maximal Non-minimal Universal Extra Dimension

Sayan Dasgupta, Ujjal Kumar Dey, Tapoja Jha +1

In this paper we consider an compactified flat extra dimensional scenario where all the standard model states can access the bulk and have generalised brane lo…

Unitarity Constraints on non-minimal Universal Extra Dimensional Model

Tapoja Jha

We examine the unitarity constraints in gauge and scalar sectors of non-minimal Universal Extra Dimensional model. We show that some of the tree-level two-body scattering amplitude…

Rare Top Decays in Minimal and Non-minimal Universal Extra Dimension

Ujjal Kumar Dey, Tapoja Jha

The flavour changing decays of the top quark are severely suppressed in the Standard Model by virtue of the Glashow-Iliopoulos-Maiani mechanism. Many beyond Standard Model extensio…

in non-minimal Universal Extra Dimensional Model

Tapoja Jha, Anindya Datta

We calculate the effective coupling at one loop level, in the framework of non-minimal Universal Extra Dimensional (nmUED) model. Non-minimality in Universal Extra Dime…
