Title: Radial and orbital excitations of static-light mesons

Abstract

We present results for the spectrum of static-light mesons from N{sub f}=2 lattice QCD. These results were obtained using all-to-all light-quark propagators on an anisotropic lattice, yielding an improved signal resolution when compared to more conventional lattice techniques. With a light-quark mass close to the strange quark, we have measured the splittings between the ground-state S-wave static-light meson and higher excitations. We attempt to identify the quantum numbers of the excited states in the context of the reduced spatial symmetries of the lattice.

  • The calculations of masses and decay constants of the radial excitations of light pseudoscalar and scalar mesons within the QCD sum rules method are briefly reviewed. The predictions are based on the 1/N{sub c}-supported model spectra, which consist of an infinite number of infinitely narrow resonances, and on the assumption that the ground states of light scalar mesons may be considered as q-barq-bound states. The results of the studies are compared with the existing experimental data and with the predictions of other theoretical approaches.
  • On the basis of the SU(6) crossO(3) quark model, the vector mesons psi (3105) and psi' (3695) are interpreted as orbital excitations of $omega$ and phi. New mesons rho-tilde (3100) (GAMMA/sub rho-tilde/
  • Inspired by the newly observed D{sub sJ}(3040){sup +} state, in this work we systemically study the two-body strong decays of P-wave charmed-strange mesons with the first radial excitation. Under the assignment of 1{sup +}(j{sup P}=(1/2){sup +}), i.e. the first radial excitation of D{sub s1}(2460){sup +}, we find that the width of D{sub sJ}(3040){sup +} is close to the lower limit of the BABAR measurement. This indicates that it is reasonable to interpret D{sub sJ}(3040){sup +} as the first radial excitation of D{sub s1}(2460){sup +}. Our calculation further predicts that 0{sup -}+1{sup -} channels, e.g., D{sup +}K*{sup 0}, D{sup 0}K*{sup +},more » and D{sub s}{sup +}{phi}, are important for the search for D{sub sJ}(3040){sup +}. To help future experiments find the remaining three P-wave charmed-strange mesons with the first radial excitation, we present the predictions for the strong decays of these three P-wave charmed-strange mesons.« less
  • Nambu's string model with spin--orbit coupling is used to calculate the spectra of orbital excitations of mesons and baryons constructed from u, d, and s quarks.
  • We discuss the mass spectrum and radiative decays of the low-lying pseudoscalar and vector mesons in a nonrelativistic potential model based on quantum chromodynamics. We are able to account successfully for the smallness of the pion mass.
