| 英文摘要 | A search for resonancelike structures in the b-s(0)pi(+/-) invariant mass spectrum is performed using proton-proton collision data collected by the cms experiment at the lhc at root s = 8 tev, corresponding to an integrated luminosity of 19.7 fb(-1). the b-s(0) mesons are reconstructed in the decay chain b-s(0) -> j/psi phi, with j/psi -> mu(+) mu(-) and phi -> k+k-. the b-s(0)pi(+/-) invariant mass distribution shows no statistically significant peaks for different selection requirements on the reconstructed b-s(0) and pi(+/-) candidates. upper limits are set on the relative production rates of the x(5568) and b-s(0) states times the branching fraction of the decay x(5568)(+/-) -> b-s(0)pi(+/-). in addition, upper limits are obtained as a function of the mass and the natural width of possible exotic states decaying into b-s(0)pi(+/-). |
