description: We report the observation of two narrow structures in the mass spectra of the π±Υ(nS) (n=1, 2, 3) and π±hb(mP) (m=1, 2) pairs that are produced in association with a single charged pion in Υ(5S) decays. The measured masses and widths of the two structures averaged over the five final states are M1=(10 607.2±2.0)  MeV/c2, Γ1=(18.4±2.4)  MeV, and M2=(10 652.2±1.5)  MeV/c2, Γ2=(11.5±2.2)  MeV. The results are obtained with a 121.4  fb−1 data sample collected with the Belle detector in the vicinity of the Υ(5S) resonance at the KEKB asymmetric-energy e+e− collider.
