| dc.description.abstract | Using 448 million psi(2S) events, the spin-singlet P-wave charmonium state h(c)(1(1)P(1)) is studied via the psi(2S) -> pi(0)h(c) decay followed by the h(c) -> gamma eta(c) transition. The branching fractions are measured to be B-Inc(psi(2S) -> pi(0)h(c)) x B-Tag (h(c) -> gamma eta(c)) = (4.22(-0.26)(+0.27) +/- 0.19) x 10(-4), B-Inc (psi(2S) -> pi(0)h(c)) = (7.32 +/- 0.34 +/- 0.41) x 10(-4) , and B-Tag (h(c) -> gamma eta(c)) = (57.66(-3.50)(+3.62) +/- 0.58)%, where the uncertainties are statistical and systematic, respectively. The h(c)(1(1)P(1)) mass and width are determined to be M = (3525.32 +/- 0.06 +/- 0.15) MeV/c(2) and Gamma = (0.78(-0.24)(+0.27)+/- 0.12) MeV. Using the center of gravity mass of the three chi(cJ) (1(3)P(J)) mesons [M(c.o.g.)], the 1P hyperfine mass splitting is estimated to be Delta(hyp) = M(h(c)) - M(c.o.g.) = (0.03 +/- 0.06 +/- 0.15) MeV/c(2), which is consistent with the expectation that the 1P hyperfine splitting is zero at the lowest order. | en_US |
