Evidence for the B-0 -> p(p)over-barK*(0) and B+->eta K-c*(+) decays and study of the decay dynamics of B meson decays into p(p)over-barh final states

With a sample of 232x10(6) Upsilon(4S)-> B (B) over bar events collected with the BABAR detector, we study the decays of B mesons to p (p) over barh final states, where h=pi(+), K-S(0), K{*}(0), or K{*}(+). We report evidence for the B-0 -> p (p) over barK({*}0) decay, with a branching fraction (1.47 +/- 0.45(stat)+/- 0.40(syst))x10(-6), and for the B+->eta K-c{*}(+) decay, with the branching fraction of B(B+->eta K-c{*}(+))xB(eta(c)-> p (p) over bar)=(1.57(-0.45)(+0.56)(stat)(-0.36)(+0.46)(syst))x10(-6), and provide improved measurements of the branching fractions of the other modes of this type. We also report the measurements of the charge asymmetry consistent with zero in the B+-> p (p) over bar pi(+), B-0 -> p (p) over barK{*}(0), and B+-> p (p) over barK{*}(+) modes. No evidence is found for the pentaquark candidate Theta(+) in the mass range 1.52 to 1.55 GeV/c(2), decaying into pK(S)(0), or the glueball candidate f(J)(2220) in the mass range 2.2 < m(p (p) over bar)< 2.4 GeV/c(2), and branching fraction limits are established for both at the 10(-7) level.
