Abstract

We study bottomonium production in association with an η meson in e+e- annihilations near the Υ(5 S) , at a centre-of-mass energy of s=10.866 GeV. The results are based on the 121.4 fb- 1 data sample collected by the Belle experiment at the asymmetric-energy KEKB collider. Only the η meson is reconstructed and the missing-mass spectrum of η candidates is investigated. We observe the e+e-→ ηΥJ(1 D) process and find evidence for the e+e-→ ηΥ(2 S) process, while no significant signals of Υ(1 S) , hb(1 P) , nor hb(2 P) are found. Cross sections for the studied processes are reported.

N2 - We study bottomonium production in association with an η meson in e+e- annihilations near the Υ(5 S) , at a centre-of-mass energy of s=10.866 GeV. The results are based on the 121.4 fb- 1 data sample collected by the Belle experiment at the asymmetric-energy KEKB collider. Only the η meson is reconstructed and the missing-mass spectrum of η candidates is investigated. We observe the e+e-→ ηΥJ(1 D) process and find evidence for the e+e-→ ηΥ(2 S) process, while no significant signals of Υ(1 S) , hb(1 P) , nor hb(2 P) are found. Cross sections for the studied processes are reported.
