Signatures of Long-Lived Heavy Neutral Leptons from Neutrinophilic Charged Higgs Pair Production at the LHC

Nobuchika Okada, Prasenjit Sanyal, Ravindra Kumar Verma

In the neutrinophilic Higgs doublet framework, the neutrino Dirac Yukawa couplings can be sizable because of the small vacuum expection value of the extra Higgs doublet, even for a…

Search for Light Scalars in the TRSM at the LHC

Aman Desai, Kristin Lohwasser, Mohamed Ouchemhou +2

We study the production of Beyond the Standard Model light scalar states in association with a vector boson (, with ) at the LHC. We consider the scenario where…

Dark Photon mediated Inelastic Dark Matter in Cosmology, Astrophysics and Colliders

Abhishek Roy, Prasenjit Sanyal, Stefano Scopel

We explore the phenomenology of Dark Photon iDM (AiDM) where the Standard Model (SM) is extended by a dark sector containing an additional gauge symmetry under…

On the CP Nature of the `95 GeV' Anomalies

Tanmoy Mondal, Stefano Moretti, Prasenjit Sanyal

Under the assumption that the various evidences of a `95 GeV' excess, seen in data at the Large Electron Positron (LEP) collider as well as the Large Hadron Collider (LHC), corresp…

Discovery Prospects for the Light Charged Higgs Boson Decay to an Off-Shell Top Quark and a Bottom Quark at Future High-Energy Colliders

Jinheung Kim, Soojin Lee, Prasenjit Sanyal +2

The charged Higgs boson () with a mass below the top quark mass remains a viable possibility within the Type-I two-Higgs-doublet model under current constraints. While previ…

Probing a Heavy Dark Boson at Multi-TeV Muon Colliders: Leveraging the Optimized Recoil Mass Technique

Kingman Cheung, Jinheung Kim, Soojin Lee +2

We investigate the discovery potential of multi-TeV muon colliders for a heavy dark boson () with a mass above 1 TeV through the associated production channel $μ^+΅
