Computing Nucleon Charges with Highly Improved Staggered Quarks
Yin Lin, Aaron S. Meyer, Steven Gottlieb +4
This work continues our program of lattice-QCD baryon physics using staggered fermions for both the sea and valence quarks. We present a proof-of-concept study that demonstrates, f…
Nucleon and Baryon Masses with All-HISQ Fermions at the Physical Point
Ciaran Hughes, Yin Lin, Aaron S. Meyer
We present the results of the nucleon and baryon masses using staggered action for both valence and sea quarks. Three ensembles with the physical pion mass at approximate latti…
Exploring S-Wave Threshold Effects in QCD: A Heavy-Light Approach
Estia Eichten, Ciaran Hughes
QCD exhibits complex dynamics near S-wave two-body thresholds. For light mesons, we see this in the failure of quark models to explain the and masses. For c…
Nucleon Mass with Highly Improved Staggered Quarks
Yin Lin, Aaron S. Meyer, Ciaran Hughes +3
We present the first computation in a program of lattice-QCD baryon physics using staggered fermions for sea and valence quarks. For this initial study, we present a calculation of…
Improving the Kinetic Couplings in Lattice Non-Relativistic QCD
Christine T. H. Davies, Judd Harrison, Ciaran Hughes +3
We improve the non-relativistic QCD (NRQCD) action by comparing the dispersion relation to that of the continuum through in perturbation theory. The one-loop mat…
Digitizing Gauge Fields: Lattice Monte Carlo Results for Future Quantum Computers
Daniel C. Hackett, Kiel Howe, Ciaran Hughes +3
In the near-future noisy intermediate-scale quantum (NISQ) era of quantum computing technology, applications of quantum computing will be limited to calculations of very modest sca…
Prompt and non-prompt J/ production and nuclear modification at mid-rapidity in p-Pb collisions at TeV
ALICE Collaboration
A measurement of beauty hadron production at mid-rapidity in proton-lead collisions at a nucleon-nucleon centre-of-mass energy TeV is presented. The semi-i…
New methods for B meson decay constants and form factors from lattice NRQCD
C. Hughes, C. T. H. Davies, C. J. Monahan
We determine the normalisation of scalar and pseudoscalar current operators made from non-relativistic quarks and Highly Improved Staggered light quarks in lattice Quantum Chro…
The Search for Beauty-fully Bound Tetraquarks Using Lattice Non-Relativistic QCD
Ciaran Hughes, Estia Eichten, Christine T. H. Davies
Motivated by multiple phenomenological considerations, we perform the first search for the existence of a tetraquark bound state with a mass below the lowest non…
Hindered M1 Radiative Decay of from Lattice NRQCD
Ciaran Hughes, Rachel J. Dowdall, Christine T. H. Davies +3
We present a calculation of the hindered M decay rate using lattice non-relativistic QCD. The calculation includes spin-dependent relativistic corrections…
Potential Energy Landscape of the Two-Dimensional XY Model: Higher-Index Stationary Points
Dhagash Mehta, Ciaran Hughes, Michael Kastner +1
The application of numerical techniques to the study of energy landscapes of large systems relies on sufficient sampling of the stationary points. Since the number of stationary po…
An Inversion-Relaxation Approach for Sampling Stationary Points of Spin Model Hamiltonians
Ciaran Hughes, Dhagash Mehta, David J Wales
Sampling the stationary points of a complicated potential energy landscape is a challenging problem. Here we introduce a sampling method based on relaxation from stationary points…
Potential Energy Landscapes for the 2D XY Model: Minima, Transition States and Pathways
Dhagash Mehta, Ciaran Hughes, Mario Schröck +1
We describe a numerical study of the potential energy landscape for the two-dimensional XY model (with no disorder), considering up to 100 spins and CPU and GPU implementations of…
Enumerating Gribov copies on the lattice
Ciaran Hughes, Dhagash Mehta, Jon-Ivar Skullerud
In the modern formulation of lattice gauge-fixing, the gauge fixing condition is written in terms of the minima or stationary points (collectively called solutions) of a gauge-fixi…
