I will present the collider phenomenology of a vector-like top partner (VLT) in the Type-II Two-Higgs-Doublet Model (2HDM-II) extended by a vector-like quark doublet, with emphasis on final states involving a charged Higgs boson. The analysis is performed in the alignment limit, where the light CP-even Higgs boson exhibits Standard Model-like properties. In this framework, the VLT...
In our study, we explored the impact of incorporating vector-like T (VLT) quarks into Two-Higgs-Doublet Models (THDMs), which introduces new decay modes beyond the Standard Model (SM) channels ($T \to Zt$, $T \to ht$, $T \to Wb$). These new beyond Standard Model (BSM) decay channels include the CP-even $T \to Ht$, CP-odd $T \to At$, and charged $T \to H^+b$, which have not been experimentally...
We examined the integration of vector-like bottom (VLB) quarks into the Two-Higgs-Doublet Model (THDM), enabling new decay channels distinct from the Standard Model (SM) processes ($B \to Zb$, $B \to hb$, $B \to Wt$). These Beyond Standard Model (BSM) decays, including CP-even $B \to Hb$, CP-odd $B \to Ab$, and charged $B \to H^-t$ modes, remain unprobed at the LHC, where VLB searches...
We investigate the LHC discovery prospects for a second Higgs doublet through $A \to ZH$ weak decay. The latter is identified as the smoking gun signature of two Higgs doublet models (2HDMs) with first-order electroweak (EW) phase transition, a necessary condition for EW baryogenesis. In the general 2HDM (G2HDM) that has flavor-changing neutral Higgs couplings, $H$ may decay dominantly via...
High-energy muon beams can generate intense and energetic muon neutrino fluxes through muon decays. The energy and intensity of the beam, as well as its well-known energy spectrum, provide a unique opportunity to study neutrino properties and interactions, potentially uncovering new physics beyond the Standard Model.
In this talk, I will discuss the prospects for detecting new scalar...
