Radiative improvement of the lattice NRQCD action using the background field method with applications to quarkonium spectroscopy
T. C. Hammant, A. G. Hart, G. M. von Hippel +2
We apply the background field (BF) method to Non-Relativistic QCD (NRQCD) on the lattice in order to determine the one-loop radiative corrections to the coefficients of the NRQCD a…
Stochastic Processes, Slaves and Supersymmetry
I. T. Drummond, R. R. Horgan
We extend the work of Tanase-Nicola and Kurchan on the structure of diffusion processes and the associated supersymmetry algebra by examining the responses of a simple statistical…
Radiative improvement of the lattice NRQCD action using the background field method and application to the hyperfine splitting of quarkonium states
T. C. Hammant, A. G. Hart, G. M. von Hippel +2
We present the first application of the background field method to Non-Relativistic QCD (NRQCD) on the lattice in order to determine the one-loop radiative corrections to the coeff…
A lattice calculation of B -> K(*) form factors
Zhaofeng Liu, Stefan Meinel, Alistair Hart +3
Lattice QCD can contribute to the search for new physics in b -> s decays by providing first-principle calculations of B -> K(*) form factors. Preliminary results are presented her…
Improved automated lattice perturbation theory in background field gauge
T. C. Hammant, R. R. Horgan, C. J. Monahan +5
We present an algorithm to automatically derive Feynman rules for lattice perturbation theory in background field gauge. Vertices with an arbitrary number of both background and qu…
Renormalization of heavy-light currents in moving NRQCD
E. H. Müller, A. Hart, R. R. Horgan
Heavy-light decays such as , and can be used to constrain the parameters of the Standard Model and in indirect searches for…
