STUDY OF ETA-C PRODUCTION IN 2-PHOTON COLLISIONS

Abstract:

Production of the ηc meson in e+e- quasireal two photon collisions has been looked for in three channels. The data were obtained from an integrated luminosity of 189 pb-1. An ηc signal is observed in two decay modes (Ks0K±π∓,π+π-π+π-) with a combined statistical significance of 3.5 standard deviations. Using the known ηc branching ratios to these channels and to K+K-π+π- the combined partial ηc width to γγ is Γγγ(ηc). The first error is statistical, and the second one includes the systematic ...
