چکیده
The first full amplitude analysis of B^{+}→J/ψϕK^{+} with J/ψ→μ^{+}μ^{-}, ϕ→K^{+}K^{-} decays is performed with a data sample of 3 fb^{-1} of pp collision data collected at sqrt[s]=7 and 8 TeV with the LHCb detector. The data cannot be described by a model that contains only excited kaon states decaying into ϕK^{+}, and four J/ψϕ structures are observed, each with significance over 5 standard deviations. The quantum numbers of these structures are determined with significance of at least 4 standard deviations. The lightest has mass consistent with, but width much larger than, previous measurements of the claimed X(4140) state.

Observation of J=ψp Resonances Consistent with Pentaquark States
Observations of exotic structures in the J=ψp channel, which we refer to as charmonium-pentaquark states, in Λb → J=ψK −p decays are presented. The data sample corresponds to an integrated luminosity of 3 fb−1 acquired with the LHCb detector from 7 and 8 TeV pp collisions. An amplitude analysis of the three-body final state reproduces the two-body mass and angular distributions. To obtain a sat...
متن کاملB?J/?(?,K) Decays within QCD Factorization Approach
We used QCD factorization for the hadronic matrix elements to show that the existing data, in particular the branching ratios BR ( ?J/?K) and BR ( ?J/??), can be accounted for this approach. We analyzed the decay within the framework of QCD factorization. We have complete calculation of the relevant hard-scattering kernels for twist-2 and twist-3. We calculated this decays in a special scale ...

متن کاملEffects of final state interaction in B^+_c to D^0 K^+ decay
In this paper, the decay of Bc+ meson, which consists of two b and c heavy quarks, into the Do and K+ mesons was studied. Given that the experimental branching ratio for this decay was within the range of 3.75*10-5 to 11.16*10-5; it was decided to calculate the theoretical branching ratio by applying the final state interaction (FSI) through the T and cross-section channels. In this process, b...
متن کاملLooking for Exotic Multiquark States in Nonleptonic B Decays *
Recent data on inclusive B decays into charmonium states taken by the CLEO collaboration suggest that a sizeable fraction of the nonleptonic decays may consist of the J/$Rp three body final state, corresponding to a distinct enhancement in the inclusive J/I/I momentum distribution. The kinematical boundary of this structure corresponds to the case where the J/~/I recoils nearly monoenergeticall...
