Abstract

First observations of χ_c0, χ_c1, and χ_c2 decays to π⁺π-K_S ⁰K_S⁰ and K⁺K^-K _S⁰K_S⁰, as well as ψ(2S) decay to π⁺π^-K_S⁰K_S ⁰, are presented. The branching fractions of these decay channels are determined using 14×10⁶ ψ(2S) events collected at BESII/BEPC. The branching fractions of χ_c0,χ _c2→K_S⁰K_S⁰ are measured with improved statistical precision.

The branching fractions of χc0,χ c2→KS0KS0 are measured with improved statistical precision.

AB - First observations of χc0, χc1, and χc2 decays to π+π-KS 0KS0 and K+K-K S0KS0, as well as ψ(2S) decay to π+π-KS0KS 0, are presented. The branching fractions of these decay channels are determined using 14×106 ψ(2S) events collected at BESII/BEPC. The branching fractions of χc0,χ c2→KS0KS0 are measured with improved statistical precision.
