A relatively light, highly bino-like dark matter in the -symmetric NMSSM and recent LHC searches
Waleed Abdallah, AseshKrishna Datta, Subhojit Roy
A highly bino-like Dark Matter (DM), which is the Lightest Supersymmetric Particle (LSP), could be motivated by the stringent upper bounds on the DM direct detection rates. This is…
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…
Two-Higgs doublet solution to the LSND, MiniBooNE and muon anomalies
Waleed Abdallah, Raj Gandhi, Samiran Roy
We show that one of the simplest extensions of the Standard Model, the addition of a second Higgs doublet, when combined with a dark sector singlet scalar, allows us to: expla…
Revisiting Generalized Two Higgs Doublet Model in the Light of Muon Anomaly and Lepton Flavor Violating Decays at HL-LHC
Nivedita Ghosh, Jayita Lahiri
One of the main motivations to look beyond the SM is the discrepancy between the theoretical prediction and observation of anomalous magnetic moment of muon. Alleviating this tensi…
Impact of high energy beam tunes on the sensitivities to the standard unknowns at DUNE
Jogesh Rout, Samiran Roy, Mehedi Masud +2
Even though neutrino oscillations have been conclusively established, there are a few unanswered questions pertaining to leptonic Charge Parity violation (CPV), mass hierarchy (MH)…
Singlet-Doublet Majorana Dark Matter and Neutrino Mass in a minimal Type-I Seesaw Scenario
Manoranjan Dutta, Subhaditya Bhattacharya, Purusottam Ghosh +1
In a bid to simultaneous explanation of dark matter (DM) and tiny but non-zero masses of left-handed neutrinos, we propose a minimal extension of the Standard Model (SM) by a vecto…
