2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/205029We report about on-going simulations of $N_f=2+1$ lattice QCD. We use a tadpole improved Symanzik gauge action and stout link smeared Wilson fermions with a clover term. We employ the Hasenbusch trick for the degenerate u- and d-quarks, and the RHMC algorithm for the simulation of the strange quark.6 pages, Contribution to Lattice 2007, Regensburg, Germany, 30 July - 4 August 2007High Energy Physics - Latticetext
