Measurement of exclusive and decays into vector-pseudoscalar final states
Abstract
Using samples of 102 million $Υ(1S)$ and 158 million $Υ(2S)$ events collected with the Belle detector, we study exclusive hadronic decays of these two bottomonium resonances to $$K^0_sK^+ \pi^-$$ and charge-conjugate (c.c.) states, $π^+π^-π^0π^0$, and $π^+π^-π^0$, and to the two-body Vector-Pseudoscalar $$(K^*(892)^0\bar{K}^0+c.c.$$, $K^*(892)^-K^++c.c.$, $ωπ^0$, and $ρπ$) final states. For the first time, signals are observed in the modes $Υ(1S)$ → $$K^0_sK^+\pi^- + c.c.$$, $π^+π^-π^0π^0$, and $Υ(2S)$$→$$π^+π^-π^0π^0$, and evidence is found for the modes $Υ(1S)$$→$$π^+π^-π^0$, $$K^*(892)^0\bar{K}^0+c.c.$$, and $Υ(2S)$ → $$K^0_sK^+\pi^- + c.c.$$ Branching fractions are measured for all the processes, while 90% confidence level upper limits on the branching fractions are also set for the modes with a statistical significance of less than $3σ$. The ratios of the branching fractions of $Υ(2S)$ and $Υ(1S)$ decays into the same final state are used to test a perturbative QCD prediction for OZI-suppressed bottomonium decays.
