Observation of a near-threshold enhancement in the e+e- -->Lambda_c+Lambda_c- cross section using initial-state radiation

G. Pakhlova

We report a measurement of the exclusive e+e- -->Lambda_c+ Lambda_c- cross section as a function of center-of-mass energy near the Lambda_c+ Lambda_c- threshold. A clear peak with…

Precise measurement of hadronic $τ$ -decays in modes with $η$ mesons

The Belle Collaboration, K. Abe

We have measured branching fractions of hadronic $τ$ decays involving an $η$ meson using 485 fb^{-1} of data collected with the Belle detector at the KEKB asymmetric-energy e^+e^-…

Observation of Two Resonant Structures in e+e- to pi+ pi- psi(2S) via Initial State Radiation at Belle

X. L. Wang, Belle Collaboration

The cross section for e+e- to pi+ pi- psi(2S) between threshold and \sqrt{s}=5.5 GeV is measured using 673 fb^{-1} of data on and off the Υ(4S) resonance collected with the Belle d…

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…

Observation of $B^{+} \to χ_{c 0} K^{+}$

K. Abe, The Belle Collaboration

We report the first observation of the decay $B^{+} \to χ_{c 0} K^{+}$ using 21.3 fb $^{- 1}$ of data collected by the Belle detector at the $Υ$ (4S) resonance. The preliminary result for…
