Moving NRQCD and B to K* gamma
Stefan Meinel, Ronald Horgan, Lew Khomskii +2
The formulation of NRQCD discretized in a reference frame boosted relative to the B rest frame will enable calculation of B form factors over a larger range of momentum transfer. W…
Automatically generating Feynman rules for improved lattice field theories
A. Hart, G. M. von Hippel, R. R. Horgan +1
Deriving the Feynman rules for lattice perturbation theory from actions and operators is complicated, especially when improvement terms are present. This physically important task…
Perturbation theory vs. simulation for tadpole improvement factors in pure gauge theories
A. Hart, R. R. Horgan, L. C. Storoni
We calculate the mean link in Landau gauge for Wilson and improved SU(3) anisotropic gauge actions, using two loop perturbation theory and Monte Carlo simulation employing an accel…
The contribution of O(alpha) radiative corrections to the renormalised anisotropy and application to general tadpole improvement schemes: addendum to "One loop calculation of the renormalised anisotropy for improved anisotropic gluon actions on a lattice" [hep-lat/0208010]
I. T. Drummond, A. Hart, R. R. Horgan +1
General O(alpha) radiative corrections to lattice actions may be interpreted as counterterms that give additive contributions to the one-loop renormalisation of the anisotropy. The…
Lattice perturbation theory for gluonic and fermionic actions
I. T. Drummond, A. Hart, R. R. Horgan +1
We calculate the two loop Landau mean links and the one loop renormalisation of the anisotropy for Wilson and improved SU(3) gauge actions, using twisted boundary conditions as a g…
One loop calculation of the renormalised anisotropy for improved anisotropic gluon actions on a lattice
I. T. Drummond, A. Hart, R. R. Horgan +1
Using the infrared dispersion relation of the on shell gluon, we calculate the renormalisation of the the anisotropy to one loop in perturbation theory for lattice Yang-Mills theor…
