Partial Wave Analysis of $χ_{c 0} \to π^{+} π^{-} K^{+} K^{-}$

M. Ablikim, BES Collaboration

A partial wave analysis of $χ_{c 0} \to π^{+} π^{-} K^{+} K^{-}$ in $ψ (2 S) \to γ χ_{c 0}$ decay is presented using a sample of 14 million $ψ (2 S)$ events accumulated by the BES II detector. The data…

Precise measurement of spin-averaged chi_{cJ}(1P) mass using photon conversions in psi(2S) -> gamma chi_{cJ}

M. Ablikim, J. Z. Bai

Using photon conversions to e^+e^- pairs, the energy spectrum of inclusive photons from psi(2S) radiative decays is measured by BESII at the Beijing Electron-Positron Collider. The…
