Abstract We study a search for the charged Higgs boson via e + e − → H + H − → c ¯ b c ¯ b $$ \overline{c}b\overline{c}b $$ at the 500 GeV ILC. In a general two Higgs doublet model without Z 2 symmetry, extra Yukawa couplings ρ tt and ρ t

Abstract We study $$R^2$$ R 2 -Higgs inflation in a model with two Higgs doublets in which the Higgs sector of the Standard Model is extended by an additional Higgs doublet, thereby four scalar fields are involved in the inflationary evolutions. We f

Starobinsky inflation is an attractive, fundamental model to explain the Planck measurements, and its higher-order extension may allow us to probe quantum gravity effects. We show that future CMB data combined with the 21cm intensity map from SKA wil

Abstract We study the prospect of probing electroweak baryogenesis driven by an extra bottom Yukawa coupling ρ bb in a general two Higgs doublet model via electric dipole moment (EDM) measurements and at the collider experiments. The parameter space

Abstract We study the correlation between the constraints on general two Higgs doublet model from Higgs inflation and from collider experiments. The parameter space receives meaningful constraints from direct searches at the large hadron collider and

We study the complementarity between the Large Hadron Collider (LHC) and future lepton colliders in probing electroweak baryogenesis induced by an additional bottom Yukawa coupling ρbb. The context is general two Higgs doublet model (g2HDM) where su

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

SKA will be a major step forward not only in astrophysics, but also in precision cosmology. We show how the neutral hydrogen intensity map can be combined with the Planck measurements of the CMB power spectrum, to provide a precision test of the infl

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

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
