2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/183860We present N_t=4 lattice results for the equation of state of 2+1 flavour staggered, dynamical QCD at finite temperature and chemical potential. We use the overlap improving multi-parameter reweighting technique to extend the equation of state for non-vanishing chemical potentials. The results are obtained along the line of constant physics. Our physical parameters extend in temperature and baryon chemical potential upto \approx 500-600 MeV.13 pages 9 figures, talk given at Finite Density QCD at Nara, Nara, Japan, 10-12 July 2003High Energy Physics - Latticetext
