Multi-photon Decays of the Higgs Boson in Standard Model: Leading Terms from Heisenberg-Euler Effective Lagrangian

Yi Liao

We calculate the multi-photon decay widths of the Higgs boson from an effective Lagrangian for a system of electromagnetic and Higgs fields. We utilize a low-energy theorem to conn…

The FSI contribution to the observed $B_{s}$ decays into $K^{+} K^{-}$ and $π^{+} K^{-}$

Xu-Hao Yuan, Hong-Wei Ke, Xiang Liu +1

Because at the tree level $B_{s} \to K^{+} K^{-}$ is Cabibbo-triple suppressed, so its branching ratio should be smaller than that of $B_{s} \to π^{+} K^{-}$ . The measurements present a r…

$Σ_{b} \to Σ_{c}$ and $Ω_{b} \to Ω_{c}$ weak decays in the light-front quark model

Hong-Wei Ke, Xu-Hao Yuan, Xue-Qian Li +2

The successful operation of LHC provides a great opportunity to study the processes where heavy baryons are involved. {In this work we mainly study} the weak transitions of $Σ_b\to…

Generalized Fierz Identities and Applications to Spin-3/2 Particles

Yi Liao, Ji-Yuan Liu

We study the most general Fierz identities for a pair of non-contracted Dirac matrices both in the standard basis and for chiral spinors. These identities are useful in building in…

Study on the effects of the light CP-odd Higgs via the leptonic decays of pseudoscalar mesons

Liang Tang, Hong-Wei Ke, Xue-Qian Li

To explain the anomalously large decay rate of $Σ^{+} \to p + μ^{+} μ^{-}$ , it was proposed that a new mechanism where a light CP-odd pseudoscalar boson of $m_{A_{1}^{0}} = 214.3$ MeV makes a cruc…

Radiative Leptonic Decays of the charged $B$ and $D$ Mesons Including Long-Distance Contribution

Ji-Chong Yang, Mao-Zhi Yang

In this work we study the radiative leptonic decays of $B^{-}$ , $D^{-}$ and $D_{s}^{-} \to γ l ν ˉ$ , including both the short-distance and long-distance contributions. The short-distance c…
