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…

The b quark mass from lattice nonrelativistic QCD
Alistair Hart, Georg von Hippel, R. R. Horgan +2
We present the first two-loop calculation of the heavy quark energy shift in lattice nonrelativistic QCD (NRQCD). This calculation allow us to extract a preliminary prediction of $…
