| Abstract: | We study bottomonium production in association with an π meson in π+πβ annihilations near the πΆ(5π), at a centre-of-mass energy of π β=10.866 GeV. The results are based on the 121.4 fbβ1 data sample collected by the Belle experiment at the asymmetric-energy KEKB collider. Only the π meson is reconstructed and the missing-mass spectrum of π candidates is investigated. We observe the π+πββππΆπ½(1π·) process and find evidence for the π+πββππΆ(2π) process, while no significant signals of πΆ(1π), βπ(1π), nor βπ(2π) are found. Cross sections for the studied processes are reported. |
