The spectrum of charmed mesons from dynamical anisotropic lattices
A. Ó Cais, M. B . Oktay, S. M. Ryan +2
We present our preliminary analysis for the chamonium and D spectra obtained from N dynamical anisotropic lattices. We use 12 lattices with lattice spacing $…
Charmonium at high temperature in two-flavor QCD
Gert Aarts, Chris Allton, Mehmet Bugrahan Oktay +2
We compute charmonium spectral functions in 2-flavor QCD on anisotropic lattices using the maximum entropy method. Our results suggest that the S-waves (J/psi and eta_c) survive up…
Radial and orbital excitations of static-light mesons
Justin Foley, Alan O'Cais, Sinead M. Ryan +1
We present results for the spectrum of static-light mesons from Nf=2 lattice QCD. These results were obtained using all-to-all light quark propagators on an anisotropic lattice, yi…
A path-integral representation of the free one-flavour staggered-fermion determinant
Francesca Maresca, Mike Peardon
Lattice fermion actions are constructed with path integrals which are equivalent to the free one-flavour staggered fermion determinant. The Dirac operators used are local and have…
Improving Algorithms to Compute All Elements of the Lattice Quark Propagator
Alan O Cais, K. Jimmy Juge, Mike J. Peardon +2
We present a new exact algorithm for estimating all elements of the quark propagator. The advantage of the method is that the exact all-to-all propagator is reproduced in a large b…
The 2+2 anisotropic Wilson gluon action with applications
Giuseppe Burgio, Alessandra Feo, Mike Peardon +1
A generalization of anisotropic lattices to include a 2+2 discretization is discussed. As a part of this program, we determine the one-loop correction to the gluon self-energy and…
