چکیده
A non-perturbative calculation of the mass of the B c UKQCD Collaboration Abstract We present a calculation of the mass of the 1 S 0 pseudoscalar bc (B c) state using a non-perturbative measurement from quenched lattice QCD. We find M Bc = 6.386(9)(98)(15) GeV where the first error is statistical, the second systematic due to the quark mass ambiguities and quenching and the third the systematic error due to the estimation of mass of the η b .

Meson B fragmentation function with consideration of mass corrections
Study of B meson (meson with the bottom quark flavor) in Large Hadron Collider (LHC) is of special importance so that the detector LHCb is devoted to investigate these types of mesons. For this reason, in this paper we will study the production process of this meson in a phenomenological approach using the experimental data from electron-positron annihilation. In this regards, we shall calculat...
متن کاملSoft Covariant Gauges on the Lattice UKQCD Collaboration
We present an exploratory study of a one-parameter family of covariant, non-perturbative lattice gauge-fixing conditions, that can be implemented through a simple Monte Carlo algorithm. We demonstrate that at the numerical level the procedure is feasible, and as a first application we examine the gauge dependence of the gluon propagator.
متن کاملB Decay Constants from NRQCD with Dynamical Fermions
We present a lattice investigation of the heavy-light meson decay constants using Wilson light quarks and NRQCD heavy quarks, partially including the effects of dynamical sea quarks. We calculate the pseudoscalar and vector decay constants over a wide range in heavy quark mass and are able to perform a detailed analysis of heavy quark symmetry. We find consistency between the extrapolation of t...
متن کاملThe Heavy-Light Spectrum from Lattice NRQCD
We present a lattice investigation of heavy-light mesons in the quenched approximation, using non-relativistic QCD for the heavy quark and a clover improved Wilson formulation for the light quark. A comprehensive calculation of the heavy-light spectrum has been performed for various heavy quark masses around the b. Our results for the Bs−Bd splitting agree well with the experimental value. We f...
متن کاملUkqcd Collaboration, Presented
We present updated results on the calculation of the matrix elements for B → K * γ in the quenched approximation on a 24 3 × 48 lattice at β=6.2, using an O(a)-improved fermion action. The scaling behaviours of the form factors T1(q 2 =0) and T2(q 2 max) for the decay are examined and pole model ansatzes tested.
