| 英文摘要 | A search is performed in the invariant mass spectrum of the b-c(+)pi(+) pi(-) system for the excited b-c(+) states b-c (2(1)s(0)) + and b-c(2(3)s(1)) + using a data sample of p p collisions collected by the lhcb experiment at the centre- of- mass energy of root s = 8tev, corresponding to an integrated luminosity of 2 fb(-1). no evidence is seen for either state. upper limits on the ratios of the production cross- sections of the bc (2(1)s(0)) + and b-c(2(3)s(1)) + states times the branching fractions of bc (2(1)s(0))(+) -> b-c(+)pi(+) pi(-) and b-c (2(3) s-1)(+) -> b-c*(+)pi(+) pi(-) over the production cross- section of the b-c(+) state are given as a function of their masses. they are found to be between 0.02 and 0.14 at 95% con fi dence level for b-c (2(1)s(0)) + and b-c (2(3)s(1)) + in the mass ranges [6830; 6890] mev/c(2) and [6795; 6890] mev/c(2), respectively. |
