Direct Measurements of Absolute Branching Fractions for D0 and D+ Inclusive Semimuonic Decays

BES Collaboration, M. Ablikim

By analyzing about 33 $p b^{- 1}$ data sample collected at and around 3.773 GeV with the BES-II detector at the BEPC collider, we directly measure the branching fractions for the…

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…

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…

Measurements of $J / ψ$ and $ψ (2 S)$ decays into $Λ Λ ˉ π^{0}$ and $Λ Λ ˉ η$

BES Collaboration, M. Ablikim

Using 58 million $J / ψ$ and 14 million $ψ (2 S)$ events collected by the BESII detector at the BEPC, branching fractions or upper limits for the decays $J / ψ$ and $ψ (2 S) \to Λ Λ ˉ π^{0}$ …

Precison Measurements of the Mass, the Widths of $ψ (3770)$ Resonance and the Cross Section $σ [e^{+} e^{-} \to ψ (3770)]$ at $E_{cm} = 3.7724$ GeV

M. Ablikim et al.

By analyzing the $R$ values measured at 68 energy points in the energy region between 3.650 and 3.872 GeV reported in our previous paper, we have precisely measured the mass, the t…
