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…

Direct measurement of the absolute branching fraction for $D^{+} \to K ˉ^{0} μ^{+} ν_{μ}$ and determination of $Γ (D^{0} \to K^{-} μ^{+} ν_{μ}) /Γ (D^{+} \to K ˉ^{0} μ^{+} ν_{μ})$

M. Ablikim

The absolute branching fraction for the decay $D^{+} \to K ˉ^{0} μ^{+} ν_{μ}$ is determined using $5321 \pm 149 \pm 160$ singly tagged $D^{-}$ sample from the data collected around 3.773 G…

Measurements of the cross sections for $e^{+} e^{-} \to hadrons$ at 3.650, 3.6648, 3.773 GeV and the branching fraction for $ψ (3770) \to non - D D ˉ$

M. Ablikim et al.

Using the BES-II detector at the BEPC Collider, we measured the lowest order cross sections and the $R$ values ( $R = σ_{e^{+} e^{-} \to hadrons}^{0} / σ_{e^{+} e^{-} \to μ^{+} μ^{-}}^{0}$ ) for incl…

Observation of a resonance X(1835) in J/ψ--> γπ^+ π^- η^{\prime}

BES Collaboration, M. Ablikim

The decay channel J/ψ--> γπ^+ π^- η^{\prime} is analyzed using a sample of 5.8\times 10^7 Jψevents collected with the BESII detector. A resonance, the X(1835), is observed in the π…

Observation of a threshold enhancement in the p \bar{Lambda} invariant mass spectrum

BES Collaboration, M. Ablikim

An enhancement near the m_p + M_Λ mass threshold is observed in the combined p \barΛ and \bar{p}Λinvariant mass spectrum from J/ψ--> p K^- \bar{Lambda} + c.c. decays. It can be fit…
