Heavy hadrons on an anisotropic lattice

چکیده
For a fixed Wilson parameter, r (usually equal to one) doublers may reappear as at is made small, which hinders simulations with at ≪ as. The solution proposed here is to treat the temporal and spatial directions differently. The temporal rotations are retained since such one-hop improvement terms ensure the transfer matrix is positive definite and no “ghost” states can propagate. Thus Eqs. 1 are modified to read

Semileptonic decays of heavy mesons into light hadrons such as, B → π lν or B → ρ lν, involve hadrons with sizeable momenta, once one moves away from the zero-recoil point at q ≡ (p − p) = q max. “pμ” is the momentum of the decaying heavy meson and “pμ” that of the light daughter meson. High momenta introduce both noise and ap discretization errors into lattice simulations making calculations o...
متن کاملLattice studies of hadrons with heavy flavors
I will discuss recent developments in lattice studies of hadrons composed of heavy quarks. I will mostly cover topics which are at a state of direct comparison with experiment, but will also discuss new ideas and promising techniques to aid future studies of lattice heavy quark physics.
متن کاملThe Mass Spectrum of Light and Heavy Hadrons from Improved Lattice Actions
We use improved lattice actions for glue, light quarks and heavy quarks for which we use lattice NRQCD to compute hadron masses. Our results are in good agreement with experiment, except for charmed hadrons. It seems that charmed quarks are not well approximated as heavy quarks nor as light quarks.
متن کاملStatic-light hadrons on a dynamical anisotropic lattice
We present preliminary results for the static-light meson and baryon spectra for N f = 2 QCD. The study is performed on an anisotropic lattice and uses a new all-to-all propagator method allowing us to determine particle masses to a high precision.
متن کاملNonperturbative study of the action parameters for anisotropic-lattice quarks
The anisotropic lattice has proved an invaluable tool for simulations of a variety of physical quantities. The precision calculation of the glueball spectrum was an early application of the approach [1] and it was recognized that anisotropic actions may also be advantageous in heavy quark physics calculations [2]. Correlators of heavy particles such as glueballs and hadrons with a charm or bott...
