Abstract We extend heavy Higgs searches at the Large Hadron Collider for $$H \rightarrow \tau \mu $$ H → τ μ by CMS, and $$H \rightarrow \tau \tau $$ H → τ τ by ATLAS and CMS, to study discovery prospects of extra Higgs states in $$pp \righta

Abstract In the general two Higgs doublet model (g2HDM) that has extra Yukawa couplings, we analyze their New Physics (NP) contributions to kaon mixing parameter ε K , direct CP violation parameter ε′/ε, and rare K + → π + ν ν ¯ $$ {K}^{+}

Abstract In a two Higgs doublet model with extra Yukawa couplings, we assess the new physics contributions to charged lepton electric dipole moment. We focus especially on muon (and tau) EDM where in the coming decade several experiments — Muon g-2

Abstract The recent confirmation of the muon $$g-2$$ g - 2 anomaly by the Fermilab $$g-2$$ g - 2 experiment may harbinger a new era in $$\mu $$ μ and $$\tau $$ τ physics. In the context of general two Higgs doublet model, the discrepancy can be exp

Abstract Purely leptonic B meson decays provide unique probes for physics Beyond the Standard Model. We study the impact of a scalar leptoquark, $$S_1$$ S1 , on $$B \rightarrow \mu \bar{\nu }$$ B→μν¯ decay. We find that, for $$m_{S_1}\sim 1\ \hb

In a general two Higgs doublet model, we study flavor changing neutral Higgs (FCNH) decays into leptons at hadron colliders, pp→ϕ0→τ∓μ±+X, where ϕ0 could be a CP-even scalar (h0, H0) or a CP-odd pseudoscalar (A0). The light Higgs boson h0

It was shown recently that, in two Higgs doublet models without Z2 symmetry, extra Yukawa couplings such as ρtc, ρtt can fuel enough CP violation for electroweak baryogenesis (EWBG). We revisit an old proposal where a pseudoscalar A0 has mass betwe

With no New Physics seen at the LHC, a second Higgs doublet remains attractive and plausible. The ratio RBμ/τ=B(B→μν¯)/B(B→τν¯) is predicted at 0.0045 in both the Standard Model and the two Higgs doublet model type II, but it can differ i

Multi-top quark production is a staple program at the LHC. Single-top and tt¯ productions are studied extensively, while current efforts are zooming in on four-top search, where the Standard Model (SM) cross section is at O(10) fb. In contrast, only
