We give results for B, Bs, Bc and bottomonium spectroscopy using NRQCD heavy quarks and HISQ valence and sea quarks. Five MILC ensembles of gluon configurations with three values of the lattice spacing and m(light)/m(strange) values down to 0.1 are used that include 2+1+1 flavours of sea quark. Systematic errors in the NRQCD action are improved through the radiative correction of the coefficients of terms at v^4. Improved results for S-wave and P-wave bottomonium states are discussed as well as… Expand

High Level Trigger softwareperformance profiling and χbproduction study at the LHCbexperiment
A software profiling tool has been developed, which helps to analyze and improve the performance of the High Level Trigger software of the LHCb experiment, able to identify spots where the execution time of the trigger application is slow, thereby allowing the optimization of thetrigger decision speed and minimizing dead times during data taking.

Precise charm to strange mass ratio and light quark masses from full lattice QCD.
By using a single formalism to handle charm, strange, and light valence quarks in full lattice QCD for the first time, we are able to determine ratios of quark masses to 1%. For m(c)/m(s) we obtainExpand

Improved nonrelativistic QCD for heavy-quark physics.
An improved version of nonrelativistic QCD is constructed for use in lattice simulations of heavy-quark physics, and power-counting rules to assess the importance of the various operators in the action and compute all leading-order corrections required by relativity and finite lattice spacing are developed.

Highly improved staggered quarks on the lattice with applications to charm physics
