چکیده

Heavy-light mesons can be studied using the 1/M expansion of NRQCD, provided the heavy quark mass is sufficiently large. Calculations of the S-wave charmed meson masses from a classically and tadpole-improved action are presented. A comparison of O(1/M), O(1/M) and O(1/M) results allows convergence of the expansion to be discussed. It is shown that the form of discretized heavy quark propagation must be chosen carefully.

S and P - wave heavy - light mesons in lattice NRQCD

The mass spectrum of S and P-wave mesons containing a single heavy quark is computed in the quenched approximation, using NRQCD up to third order in the inverse heavy quark mass expansion. Previous results found the expansion to break down near the charm quark mass for the S-wave spin splitting. The present work considers variations such as anisotropic lattices, Landau link tadpole improvement,...

The charmed and bottom meson spectrum from lattice NRQCD

B (∗) s ) are well known experimentally, and thus provide a testing ground for the lattice method. In particular, they can be used to examine the convergence properties of the heavy quark expansion in nonrelativistic QCD (NRQCD),[1] which is the most economical lattice action available for heavy quark physics.[2] The spectrum of P-wave heavy-light mesons is not yet understood, experimentally no...

Heavy-light meson spectrum with and without NRQCD

If the charm quark is sufficiently heavy, then lattice NRQCD is an efficient computational method for obtaining the spectrum of mesons with a single charm quark. Recent studies of the S and P-wave meson spectrum have determined the contributions from first, second and third order in the inverse charm mass expansion.[1,2] Second and third order contributions were found to be statistically insign...

O ( 1 / M 3 ) effects for heavy - light mesons in lattice NRQCD

The masses of S0 and S1 mesons containing a single heavy quark are computed in the quenched approximation. The light quark action and gauge field action are both classically-improved and tadpole-improved, and the couplings to the heavy quark are organized by the 1/M expansion of tadpole-improved NRQCD. At each of two lattice spacings, near 0.22fm and 0.26fm, meson masses are obtained for heavy ...

Moving NRQCD

Many of the most interesting experimental probes of the Standard Model involve exclusive weak decays of B mesons. Because the B is much heavier than charmed and strange mesons, these decay products have large recoil momenta. This presents a problem for lattice calculations of these processes, since (naively) the spatial lattice spacing must be fine enough to control discretization errors of ord...
