FASTSUM Generation 2 Anisotropic Thermal Lattice QCD Gauge Ensembles
<p><strong>FASTSUM Generation 2 Anisotropic Thermal Lattice QCD Gauge Ensembles</strong></p> <p> </p> <p>The FASTSUM collaboration <a href="https://fastsum.gitlab.io/">[1]</a> Generation 2 Ensembles are lattice Quantum Chromodynamics (QCD) gauge-ensembles used extensively to examine thermal (non-zero temperature) properties of QCD using the first principles methods of lattice QCD. These are anisotropic lattices using the `fixed-scale` approach to thermal ensembles wherein the temperature is changed entirely by changing the number of points in the temporal direction.</p> <p> </p> <p>These ensembles are freely available (see below). The only requirements of use are that this Zenodo page, and the two papers detailing the ensembles, <a href="https://doi.org/10.1007/JHEP02(2015)186">Electrical conductivity and charge diffusion in thermal QCD from the lattice</a> and <a href="https://link.aps.org/doi/10.1103/PhysRevD.105.034504">Properties of the QCD thermal transition with Nf=2+1 flavors of Wilson quark</a> are appropriately cited.</p> <p>These ensembles are characterised by</p> <ul> <li>\(N_f = 2 +1 \) flavour <ul> <li>Degenerate up and down quarks, physical strange quark</li> </ul> </li> <li>spatial lattice spacing \(a_s\) <ul> <li>~0.12 fm</li> </ul> </li> <li>temporal lattice spacing \(a_t\) <ul> <li>~0.035 fm</li> </ul> </li> <li>anisotropy \(\nu = a_s / a_t\) <ul> <li>~3.444</li> </ul> </li> <li>Number of spatial sites NS <ul> <li>NS = 24 or 32</li> </ul> </li> <li>Number of Temporal sites <ul> <li>NT in [16, 48]</li> </ul> </li> <li>Temperatures <ul> <li>117 MeV to 352 MeV</li> </ul> </li> <li>Pseudocritical temperature (from renormalised chiral condensate) <ul> <li>181(1) MeV</li> </ul> </li> <li>Pion mass <ul> <li>\(m_\pi \sim 384\) MeV</li> </ul> </li> <li>Pseudoscalar to vector mass ratio <ul> <li>\( M_\pi / M_\rho \sim 0.446\)</li> </ul> </li> </ul> <p> </p> <p>This choice action and bare parameters follows that of the Hadron Spectrum Collaboration <a href="https://doi.org/10.1103/PhysRevD.78.054501">https://doi.org/10.1103/PhysRevD.78.054501</a>, namely a Symanzik improved gauge action and a tadpole improved Wilson-clover fermion action with stout-smeared links. </p> <p>The main parameters in the lattice action are listed below.
