We study an extension of the Standard Model with two complex scalar singlets, and , charged under and , respectively, and a muon-philic vect…
Electroweak phase transitions in a extension of the standard model with dimension-six operators: Gravitational waves and LHC signatures
Arka Bhattacharyya, Sanjoy Biswas, Saurabh Niyogi
We investigate the possibility of realizing strong first-order electroweak phase transition (SFOEWPT) in an effective field theory framework where the Standard Model is extended wi…
Revisiting Singlet Fermion Dark Matter with a Scalar Portal: Connecting Higgs Phenomenology and Strong Electroweak Phase Transition
Jaydeb Das, Saurabh Niyogi, Tripurari Srivastava
We investigate a minimal extension of the Standard Model with a real singlet scalar and a singlet Dirac fermion acting as dark matter. Unlike a conventional singlet scalar setup, w…
Search for Stochastic GW Signal as a Complementary Approach to Multi-Higgs Productions at the Hadron Colliders to Probe Dimension Six Operator
Dilruba Gazi, Abhi Mukherjee, Saurabh Niyogi +1
We have considered an effective field theory framework in which the Standard Model is extended by a non-renormalizable dimension six operator () resp…
Prospects of Gluino searches in multi-lepton channels in the light of ongoing LHC RUN-III
Abhi Mukherjee, Saurabh Niyogi, Sujoy Poddar +1
This study investigates the prospect of discovering strongly interacting gluinos in different multi-lepton channels with lepton multiplicity greater than or equal to 2 at LHC RUN-I…
Revisiting the gluino mass limits in the pMSSM in the light of the latest LHC data and Dark Matter constraints

The purpose of this paper is to examine the model dependence of the stringent constraints on the gluino mass obtained from the Large Hadron Collider (LHC) experiments by analyzing…
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…

We investigate the production and decays of doubly-charged Higgs bosons for the Type-II seesaw mechanism at an collider with two center of mass energies, $\sqrt{s}=38…
Non-Standard Neutrino Interactions : Obviating Oscillation Experiments
Debajyoti Choudhury, Kirtiman Ghosh, Saurabh Niyogi
Searching for non-standard neutrino interactions, as a means for discovering physics beyond the Standard Model, has one of the key goals of dedicated neutrino experiments, current…
Revisiting the non-resonant Higgs pair production at the HL-LHC
Amit Adhikary, Shankha Banerjee, Rahool Kumar Barman +2
We study the prospects of observing the non-resonant di-Higgs pair production in the Standard Model (SM) at the high luminosity run of the 14 TeV LHC (HL-LHC), upon combining multi…

Sabyasachi Chakraborty, Saurabh Niyogi, K. Sridhar
A compressed spectrum is an anticipated hideout for many beyond standard model scenarios. Such a spectrum naturally arises in the minimal universal extra dimension framework and al…
