Orbitally excited and hybrid mesons from the lattice.
We discuss in general the construction of gauge-invariant non-local meson operators on the lattice. We use such operators to study the P and D-wave mesons as well as hybrid mesons in quenched QCD, with quark masses near the strange quark mass. The resulting spectra are compared with experiment for the orbital excitations. For the states produced by gluonic excitations (hybrid mesons) we find ev...
متن کاملObservation of orbitally excited B(s) mesons.
We report the observation of two narrow resonances consistent with states of orbitally excited (L=1) B_(s) mesons using 1 fb;(-1) of pp[over ] collisions at sqrt[s]=1.96 TeV collected with the Collider Detector at Fermilab II detector at the Fermilab Tevatron. We use two-body decays into K- and B+ mesons reconstructed as B(+)-->J/psiK(+), J/psi-->mu(+)mu(-) or B(+)-->D[over ](0)pi(+), D[over ](...
متن کاملProperties of Orbitally Excited Heavy-Light Mesons
Orbitally excited heavy-light mesons are potentially important as tools for tagging the flavors and momenta of ground-state pseudoscalars detected through weak decays. We use heavy-quark symmetry supplemented by insights gleaned from potential models to estimate masses and widths of p-wave B, Bs, and Ds mesons. We generalize these results to higher excitations. PACS numbers: 14.40.Jz, 13.25.+m,...
متن کاملExcited B mesons from the lattice
We determine the energies of the excited states of a heavy-light meson Q¯ q, with a static heavy quark and light quark with mass approximately that of the strange quark from both quenched lattices and with dynamical fermions. We are able to explore the energies of orbital excitations up to L=3, the spin-orbit splitting up to L=2 and the first radial excitation. These b¯ s mesons will be very na...
متن کاملHybrid mesons from lattice QCD
Recent lattice simulation studies of heavy-quark hybrid mesons in which the quark and antiquark are bound together by an excited gluon field are summarized. Hybrid mesons are states in which a valence quark and an antiquark are bound by an excited gluon field. Interest in such states has been recently sparked by observations of resonances with exotic 1 quantum numbers[1]. In fact, the proposed ...
