Charmed Strange Mesons from Lattice QCD with Overlap Fermions
نویسندگان
چکیده
The charmed-strange meson mases are calculated on a quenched lattice QCD. The charm and strange quark propagators are calculated on the same lattice with the overlap fermion. 16 3 × 72 lattices with Wilson gauge action at β = 6.3345 are used. The charm and strange quark masses are determined by fitting the J/ψ and φ masses respectively. The charmed strange meson spectrum for the scalar, axial, pseudoscalar and vector channels are calculated. They agree with experiments. In particular, we find the scalar meson mass to be 2248(78) MeV which is in agreement with that of D * s0 (2317).

D K scattering and the D s spectrum from lattice QCD
We present results from Lattice QCD calculations of the low-lying charmed-strange meson spectrum using two types of Clover-Wilson lattices. In addition to quark-antiquark interpolating fields we also consider meson-meson interpolators corresponding to D-meson kaon scattering states. To calculate the all-to-all propagation necessary for the backtracking loops we use the (stochastic) distillation...
متن کاملScalar glueball and meson spectroscopy in unquenched lattice QCD with improved staggered quarks
We present results of an exploratory study of singlet scalar states in unquenched QCD using both glueball and meson operators. Results for non-singlet non-strange scalar mesons are also presented. We use Asqtad improved staggered fermions and gauge configurations generated by the MILC collaboration at lattice spacings of .12 and .09 fm. In this formulation, the glueball mass is not significantl...
متن کاملCalculation of the nucleon sigma term and strange quark content with two flavors of dynamical overlap fermions
We present a calculation of the nucleon sigma term on two-flavor QCD configurations with dy-namical overlap fermions. We analyse the lattice data for the nucleon mass using the baryon chiral perturbation theory. Using partially quenched data sets, we extract the connected and disconnected contributions to the nucleon sigma term separately. Chiral symmetry on the lattice simplifies the determina...
متن کاملPreliminary results from a simulation of quenched QCD with overlap fermions on a large lattice
We simulate quenched QCD with the overlap Dirac operator. We work with the Wilson gauge action at β = 6 on an 18 3 × 64 lattice. We calculate quark propagators for a single source point and quark mass ranging from amq = 0.03 to 0.75. We present here preliminary results based on the propagators for 60 gauge field configurations. 1. Introduction The closely related domain wall [1,2] and overlap [...
متن کاملMeson spectral functions with chirally symmetric lattice fermions
In order to enhance our understanding of spectral functions in lattice QCD obtained with the help of the Maximum Entropy Method, we study meson spectral functions for lattice fermions with chiral symmetry. In particular we analyse lattice artefacts for standard overlap, overlap hypercube and domain wall fermions in the free field limit. We also present first results for pseudoscalar spectral fu...
