Title: First Observation of the Hadronic Transition Υ ( 4 S ) η h b ( 1 P ) and New Measurement of the h b ( 1 P ) and η b ( 1 S ) Parameters

Abstract

Using a sample of 771.6 × 10 6 Υ Υ ( 4 S ) decays collected by the Belle experiment at the KEKB e + e - collider, we observe, for the first time, the transition Υ ( 4 S ) η h b ( 1 P ) with the branching fraction B [ Υ ( 4 S ) η h b ( 1 P ) ] = ( 2.18 ± 0.11 ± 0.18 ) × 10 - 3 and we measure the h b ( 1 P ) mass M h b ( 1 P ) = ( 9899.3 ± 0.4 ± 1.0 ) MeV / c 2 , corresponding to the hyperfine (HF) splitting Δ M HF ( 1 P ) = ( 0.6 ± 0.4 ± 1.0 ) MeV / c 2 . Using the transition h b ( 1 P ) γ η b ( 1 S ) , we measure the η b ( 1 S ) mass M η b ( 1 S ) = ( 9400.7 ± 1.7 ± 1.6 ) MeV / c 2 , corresponding to Δ M HF ( 1 S ) = ( 59.6 ± 1.7 ± 1.6 ) MeV / c 2 , the η b ( 1 S ) width Γ η b ( 1 S ) = ( 8 - 5 + 6 ± 5 ) MeV / c 2 and the branching fraction B [ h b ( 1 P ) γ η b ( 1 S ) ] = ( 56 ± 8 ± 4 ) % .
