| 英文摘要 | A search for the decays of the b-c(+) meson to p (p) over bar pi(+) is performed for the first time using a data sample corresponding to an integrated luminosity of 3.0 fb(-1) collected by the lhcb experiment in pp collisions at centre-of-mass energies of 7 and 8 tev. no signal is found and an upper limit, at 95% confidence level, is set, f(c)/f(u) x b(b-c(+) -> p (p) over bar pi(+)) < 3.6 x 10(-8) in the kinematic region m(p<(p)over bar>) < 2.85 gev/c(2), p(t)(b) < 20 gev/c and 2.0 < y(b) < 4.5, where b is the branching fraction and f(c)(f(u)) is the fragmentation fraction of the b quark into a b-c+(b+) meson.
