Charged-Higgs on $R_{D^{(*)}}$ , $τ$ polarization, and FBA

Chuan-Hung Chen, Takaaki Nomura

We study the influence of a charged-Higgs on the excess of branching fraction ratio, $R_{M} = B R (B ˉ \to M τ ν ˉ_{τ}) / B R (B ˉ \to M ℓ ν ˉ_{ℓ})$ $(M = D, D^{*})$ , in a generic…

$S U (2)_{X}$ Vector DM and Galactic Center Gamma-Ray Excess

Chuan-Hung Chen, Takaaki Nomura

An unbroken $Z_{3}$ symmetry remains when local $S U (2)_{X}$ is broken spontaneously by one quadruplet. The gauge boson $χ_{μ} (χ ˉ_{μ})$ carries the dark charge and is the candidate of d…

$∣ V_{u b} ∣$ and $B \to η^{(^{'})}$ Form Factors in Covariant Light Front Approach

Chuan-Hung Chen, Yue-Long Shen, Wei Wang

$B \to (π, η, η^{'})$ transition form factors are investigated in the covariant light-front approach. With theoretical uncertainties, we find that $B \to (π, η, η^{'})$ form factors at $q^…
