title = "Study of hc(1P1) at BESIII",
abstract = "Inclusive measurements of the spin-singlet P-wave state of charmonium hc(1P1) have been performed with a sample of approximately 106 millionψ(2S) decays collected with the BESIII detector at the BEPCII electron-positron storage ring. We fitted distributions of the mass recoiling against the π0 in the decay ψ(2S)→π0hc both inclusively and with a tag of the E1-transition photon from h c→γhc to obtain the following preliminary results: M(hc) = 3525:16±0:16(stat:) MeV; Γ(h c) = 0:89±0:57(stat:) MeV; B(ψ(2S) →π0hc) = (8:42±1:29(stat:)×10 -4; B(ψ(2S) →π0hc)×B(h c→γηc) = (4:69±0:48(stat:) ×10-4; and B(hc→γηc) = (55:7±6:3(stat:))%:",
