| 英文摘要 | The dalitz plot analysis technique is used to study the resonant substructures of b- -> d+pi(-)pi(-) decays in a data sample corresponding to 3.0 fb(-1) of pp collision data recorded by the lhcb experiment during 2011 and 2012. a model-independent analysis of the angular moments demonstrates the presence of resonances with spins 1, 2 and 3 at high d+pi(-) mass. the data are fitted with an amplitude model composed of a quasi-model-independent function to describe the d+pi(-) s wave together with virtual contributions from the d*(2007)(0) and b*(0) states, and components corresponding to the d-2*(2460)(0), d-1*(2680)(0), d-3*(2760)(0) and d-2*(3000)(0) resonances. the masses and widths of these resonances are determined together with the branching fractions for their production in b- -> d+pi(-)pi(-) decays. the d+pi(-) s wave has phase motion consistent with that expected due to the presence of the d-0*(2400)(0) state. these results constitute the first observations of the d-3*(2760)(0) and d-2*(3000)(0) resonances, with significances of 10 sigma and 6.6 sigma, respectively. |
