Small amplitude effects in B 0 → D + D − and related decays
Intrigued by a recent Belle result for a large direct CP asymmetry in B → D+D−, we study the effects of a b̄ → ūud̄ quark transition by combining the asymmetry information with rates and asymmetries in isospin-related decays. Arguing for a hierarchy among several contributions to these decays, including an exchange amplitude which we estimate, we present tests for factorization of the leading ter...
متن کاملAmplitude analysis of Bþ → J=ψφKþ decays
R. Aaij et al. (LHCb Collaboration) (Received 25 June 2016; published 11 January 2017) The first full amplitude analysis of Bþ → J=ψφKþ with J=ψ → μþμ−, φ → KþK− decays is performed with a data sample of 3 fb−1 of pp collision data collected at ffiffi s p 1⁄4 7 and 8 TeV with the LHCb detector. The data cannot be described by a model that contains only excited kaon states decaying into φKþ, and...
متن کاملAmplitude analysis of B− → Dþπ−π− decays
R. Aaij et al. (LHCb Collaboration) (Received 4 August 2016; published 5 October 2016) The Dalitz plot analysis technique is used to study the resonant substructures of B− → Dþπ−π− 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...
متن کاملAmplitude analysis of B0 → D̄0Kþπ− decays
The Dalitz plot distribution of B → D̄0Kþπ− decays is studied using a data sample corresponding to 3.0 fb−1 of pp collision data recorded by the LHCb experiment during 2011 and 2012. The data are described by an amplitude model that contains contributions from intermediate K ð892Þ0, K ð1410Þ0, K 2ð1430Þ and D 2ð2460Þ resonances. The model also contains components to describe broad structures, in...
متن کاملSmall Scale Effects on the Large Amplitude Nonlinear Vibrations of Multilayer Functionally Graded Composite Nanobeams Reinforced with Graphene-Nanoplatelets
The main purpose of the present investigation is to analyze more comprehensively the size-dependent nonlinear free vibration response of multilayer functionally graded graphene platelet-reinforced composite (GPLRC) nanobeams. As a consequence, both of the hardening stiffness and softening stiffness of size effect are taken into consideration by implementation of the nonlocal str...
