Search for Light Scalars in the Two Real Singlet Model at the LHC
Aman Desai, Kristin Lohwasser, Mohamed Ouchemhou +2
We investigate exotic scalar decays in the Two Real Singlet Model (TRSM), focusing on light CP-even scalars with ~GeV and $20 \le M_{2} \le 1…
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 (IDM) where the Standard Model (SM) is extended by a dark sector containing an additional gauge symmetry with cou…
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^+μ^…
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…
via electroweak multi-Higgs production as smoking gun signals for Type-I 2HDM at the LHC
Prasenjit Sanyal, Tanmoy Mondal, Stefano Moretti +1
Extending the Standard Model (SM) by one additional Higgs doublet leads to the Two-Higgs Doublet Model (2HDM). A specific charge assignment of the SM fermions under the $\mathbb{Z}…
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 Light Fermiophobic Higgs Boson via diphoton jets at the HL-LHC
Daohan Wang, Jin-Hwan Cho, Jinheung Kim +3
In this study, we explore the phenomenological signatures associated with a light fermiophobic Higgs boson, , within the type-I two-Higgs-doublet model at the HL-LHC. Ou…
Probing the electroweak final state in type I 2HDM at the LHC
Prasenjit Sanyal, Daohan Wang
Most of the experimental searches of the non-Standard Model Higgs boson(s) at the LHC rely on the QCD induced production modes. However, in some beyond Standard Model frameworks, t…
Electroweak Multi-Higgs Production: A Smoking Gun for the Type-I Two-Higgs-Doublet Model
Tanmoy Mondal, Stefano Moretti, Shoaib Munir +1
Extending the Higgs sector of the Standard Model (SM) by just one additional Higgs doublet field leads to the two-Higgs-doublet model (2HDM). In the Type-I -symmetric limit of…

Jinheung Kim, Soojin Lee, Prasenjit Sanyal +2
The light fermiophobic Higgs boson in the type-I two-Higgs-doublet model can evade the current search programs at the LHC since its production through the quark-antiqua…
Fermiophobic light Higgs boson in the type-I two-Higgs-doublet model
Jinheung Kim, Soojin Lee, Prasenjit Sanyal +1
The null results in the new physics searches at the LHC do not exclude an intermediate-mass new particle if it is fermiophobic. Type-I in the two-Higgs-doublet model accommodates a…

We explored the prospect of looking for a fermiophobic charged Higgs ($\hpm$) via the same sign trilepton signal at the LHC. A fermiophobic scenario appears in the type-I two Higgs…
