Branching fraction measurement of J/ψ→KSKL and search for J/ψ→KSKS

Using a sample of 1.31×109  J/ψ events collected with the BESIII detector at the BEPCII collider, we study the decays of J/ψ→KSKL and KSKS. The branching fraction of J/ψ→KSKL is determined to be B(J/ψ→KSKL)=(1.93±0.01(stat)±0.05(syst))×10−4, which significantly improves on previous measurements. No...

Description
Summary:Using a sample of 1.31×109  J/ψ events collected with the BESIII detector at the BEPCII collider, we study the decays of J/ψ→KSKL and KSKS. The branching fraction of J/ψ→KSKL is determined to be B(J/ψ→KSKL)=(1.93±0.01(stat)±0.05(syst))×10−4, which significantly improves on previous measurements. No clear signal is observed for the J/ψ→KSKS process, and the upper limit at the 95% confidence level for its branching fraction is determined to be B(J/ψ→KSKS)
