Top-Quark FCNC Decay t->cgg in Topcolor-assisted Technicolor Model

Huan-Jun Zhang

The topcolor-assisted technicolor (TC2) model predicts several pseudo-scalars called top-pions and at loop level they can induce the FCNC top quark decay t->cgg which is extremely…

Observation of Y(2175) in $J / ψ \to η ϕ f_{0} (980)$

BES Collaboration, M. Ablikim

The decays of $J / ψ \to η ϕ f_{0} (980) (η \to γ γ, ϕ \to K^{+} K^{-}, f_{0} (980) \to π^{+} π^{-})$ are analyzed using a sample of $5.8 \times 1 0^{7}$ $J / ψ$ events collected with the BESII detector at the…

The rare decays $B_{u}^{+} \to π^{+} ℓ^{+} ℓ^{-}$ , $ρ^{+} ℓ^{+} ℓ^{-}$ and $B_{d}^{0} \to ℓ^{+} ℓ^{-}$ in the R-parity violating supersymmetry

Jian-Jun Wang, Ru-Min Wang, Yuan-Guo Xu +1

We study the rare decays $B_{u}^{+} \to π^{+} ℓ^{+} ℓ^{-}$ , $ρ^{+} ℓ^{+} ℓ^{-}$ and $B_{d}^{0} \to ℓ^{+} ℓ^{-} (ℓ = e, μ)$ in the R-parity violating supersymmetric standard…

Study of $B_{c}^{-}$ $\to$ $J / ψ π^{-}$ , $η_{c} π^{-}$ Decays with QCD Factorization

Junfeng Sun, Guifeng Xue, Yueling Yang +2

The $B_{c}$ $\to$ $J / ψ π$ , $η_{c} π$ decays are studied in the scheme of the QCD factorization approach. The branching ratios are calculated with the asymptotic distribution amplit…

Search for the C-parity violating process J/psi->gamma gamma via psi(2S)->pi+pi- J/psi

M. Ablikim, J. Z. Bai

Using 14.0\times 10^6 ψ(2S) events collected with the BES-II detector, the C-parity violating process J/psi->gamma gamma via psi(2S)->pi+pi- J/psi is studied. We determine a new up…
