Non-Spectator Diquark Effects on Lifetimes of Λ_b, Ω_{b}^{()} and Weak Decay Rates of Σ_{b}^{()}, Ξ_{b}^{(*)}

Wu-Sheng Dai, Xin-Heng Guo, Xue-Qian Li +1

The difference of τ_{_B} and τ_{_{Λ_b}} indicates the role of the light flavors. We calculate the lifetimes of B-meson and Λ_b based on the weak effective Hamiltonian while assumin…

Determine the parameter Bk of the K0-K0bar system by means of the precise Cabibbo-Kobayashi-Maskawa matrix elements

Yong Liu, Jing-Ling Chen, Wu-Sheng Dai

Taking use of the relation between weak CP phase and the other three mixing angles in Cabibbo-Kobayashi-Maskawa matrix postulated by us before, the uncertainty coming from the weak…

Study on $ν_{μ}$ , $ν_{τ}$ Decays and CP-Non Invariance at Early Epoch of the Universe

Wu-Sheng Dai, Song Gao, Xue-Qian Li

We study the $ν_{μ}$ and $ν_{τ}$ decays in the early epoch of the universe. If $m_{ν_{τ}} > 2 m_{e}$ , there would be a CP asymmetry between $ν_{τ} \to e^{+} + e^{-} + ν_{e}$ and $\barν_τ \rightarr…
