چکیده

The quantum numbers of the X(3872) meson are determined to be J(PC)=1(++) based on angular correlations in B(+)→X(3872)K(+) decays, where X(3872)→π(+)π(-)J/ψ and J/ψ→μ(+)μ(-). The data correspond to 1.0 fb(-1) of pp collisions collected by the LHCb detector. The only alternative assignment allowed by previous measurements J(PC)=2(-+) is rejected with a confidence level equivalent to more than 8 Gaussian standard deviations using a likelihood-ratio test in the full angular phase space. This result favors exotic explanations of the X(3872) state.

Belle data for the ππ mass spectrum in X(3872) → π + π − J/Ψ are well fitted by ρ + J/Ψ with J P C = 1 ++ , but are poorly fitted by the ππ S-wave.

Production of the X( 3872) in B-meson decay by the coalescence of charm mesons.

If the recently discovered charmonium state X( 3872) is a loosely bound S-wave molecule of the charm mesons D0 D(*0) or D(*0) D0, it can be produced in B-meson decay by the coalescence of charm mesons. If this coalescence mechanism dominates, the ratio of the differential rate for B+ -->D(0) D(* 0)K+ near the D0 D(*0) threshold and the rate for B+ -->XK+ is a function of the D0 D(*0) invariant ...

X ( 3872 ) and Y ( 4140 ) using diquark - antidiquark operators with lattice QCD

We discuss a recent lattice study of charmonium-like mesons with JPC = 1++ and three quark contents c̄cd̄u, c̄c(ūu+ d̄d) and c̄cs̄s, where the latter two can mix with c̄c. In this quantum channel, the long known exotic candidate, X(3872), resides. This simulation employs N f = 2, mπ = 266 MeV and a large basis of c̄c, two-meson and diquark-antidiquark interpolating fields, with diquarks in both anti-tr...

Belle data for the ππ mass spectrum in X(3872) → π + π − J/Ψ are well fitted by ρ + J/Ψ with J P C = 1 ++ , but are poorly fitted by the ππ S-wave. This rules out quantum numbers 1 +− , 2 −− and 3 −−. Formulae for partial wave amplitudes are given for all likely J P C and decay modes of the 3941 MeV peak which Belle observe in ω + J/Ψ.
