Psi(2S) two- and three-body hadronic decays

BES Collaboration, J. Z. Bai

We report measurements of branching fractions for psi(2S) decays into omega pi pi, b1 pi,omega f2(1270),omega KK, omega p pbar, phi pi pi, phi f0(980),phi KK, and an upper limit fo…

First Measurement of the Branching Fraction of the Decay psi(2S) --> tau tau

J. Z. Bai

The branching fraction of the psi(2S) decay into tau pair has been measured for the first time using the BES detector at the Beijing Electron-Positron Collider. The result is $B_{τ…

Study of the Hadronic Decays of χ_c States

J. Z. Bai

Hadronic decays of the P-wave spin-triplet charmonium states χ_cJ (J=0,1,2) are studied using a sample of ψ(2S) decays collected by the BES detector operating at the BEPC storage r…

Branching Fractions for $ψ (2 S) t o γ η^{'}$ and $γ η$

J. Z. Bai

We report the first measurements of the branching fractions: $B (ψ (2 S) - > γ η^{'}) = (1.54 \pm 0.31 \pm 0.23) x 1 0^{- 4}$ and $B (ψ (2 S) - > γ η) = (0.53 \pm 0.31 \pm 0.08) x 1 0^{- 4}$ . The $…
