Search prospect for electrophilic bosons at the TRISTAN
Amit Adhikary, Anindya Datta, Dilip Kumar Ghosh
Mediators coupled predominantly to the electron remain weakly constrained above the kinematic reach of the ~factories, a region that is difficult to access at hadron colliders a…
ALP and boson at the Electron-Ion collider
Amit Adhikary, Dilip Kumar Ghosh, Sk Jeesun +1
We study the sensitivity of the upcoming electron-ion (EIC) collider to purely electrophilic new physics in the GeV mass range. Within an effective field theory framework, we consi…
Prospects for sub-EW-scale ALP searches via signatures at the LHC using jet substructure techniques
Amit Adhikary, Aoife Bharucha, Lorenzo Feligioni +1
The current Large Hadron Collider (LHC) data show no clear indication of new physics and only incremental improvements are anticipated at the energy frontier in the near future. Ho…
Exploring the Singlino-dominated Thermal Neutralino Dark Matter in the invariant NMSSM
Amit Adhikary, Rahool Kumar Barman, Biplob Bhattacherjee +2
We examine the parameter space of the Next to Minimal Supersymmetric Standard Model (NMSSM) with Singlino-dominated neutralino as the lightest supersymmetric part…
Theoretical constraints on models with vector-like fermions
Amit Adhikary, Marek Olechowski, Janusz Rosiek +1
We provide a set of theoretical constraints on models in which the Standard Model field content is extended by vector-like fermions and in some cases also by a real scalar singlet.…
New realisation of light thermal dark matter with enhanced detection prospects
Amit Adhikary, Debasish Borah, Satyabrata Mahapatra +3
Light dark matter (DM) with mass around the GeV scale faces weaker bounds from direct detection experiments. If DM couples strongly to a light mediator, it is possible to have obse…
Status of G2HDM with right handed neutrino coupling in the light of anomalies
Nilakshi Das, Amit Adhikary, Rupak Dutta
Recent experimental measurements of several observables in semileptonic B meson decays have pointed towards the possibility of new physics. The LHCb collaboration has reported a si…
Prospects for exotic decays in single and di-Higgs boson production at the LHC and future hadron colliders
Amit Adhikary, Shankha Banerjee, Rahool Kumar Barman +5
We study the prospects for observing exotic decays of the Standard Model Higgs boson into light beyond the Standard Model scalars with mass in the…
Long live The NMSSM!
Amit Adhikary, Rahool Kumar Barman, Biplob Bhattacherjee +3
We analyze the scenario within the Next to Minimal Supersymmetric Standard Model (NMSSM), where the lightest supersymmetric particle (LSP) is singlino-like neutralino. By systemati…
Probing the interaction at the high energy upgrade of the LHC
Amit Adhikary, Nabarun Chakrabarty, Indrani Chakraborty +1
An interaction at the tree level is common feature of new physics models that feature scalar triplets. In this study, we aim to probe the strength of the aforementi…
Prospects of non-resonant di-Higgs searches and Higgs boson self-coupling measurement at the HE-LHC using machine learning techniques
Amit Adhikary, Rahool Kumar Barman, Biplob Bhattacherjee
The prospects of observing the non-resonant di-Higgs production in the Standard Model at the proposed high energy upgrade of the LHC, the HE-LHC( a…
Searching for heavy Higgs in supersymmetric final states at the LHC
Amit Adhikary, Biplob Bhattacherjee, Rohini M. Godbole +2
In this work, we analyse and demonstrate possible strategies to explore extended Higgs sector of the Minimal Supersymmetric Standard Model (MSSM). In particular we concentrate on h…
Resonant heavy Higgs searches at the HL-LHC
Amit Adhikary, Shankha Banerjee, Rahool Kumar Barman +1
In this work, we show the importance of searches for heavy resonant scalars () and pseudoscalars (). Taking cue from the present searches, we make projections for searches in…
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…
