Using a sample of 122×10^6 Υ(3S) events recorded with the BABAR detector at the PEP-II asymmetric-energy e+e- collider at SLAC, we search for the hb(1P) spin-singlet partner of the P-wave χbJ(1P) states in the sequential decay Υ(3S)→π0hb(1P), hb(1P)→γηb(1S). We observe an excess of events above background in the distribution of the recoil mass...
