Properties 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 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 کاملUniversal Behavior in Excited Heavy - Light and Light - Light Mesons
A common pattern of large orbital and radial excitations in heavy-light and lightlight mesons is demonstrated. Within a general potential model the Regge slopes of the light degrees of freedom for these mesons are shown to be in the ratio of two. The possibility of \tower" degeneracy occurs only with pure scalar con nement.
