Summary, in English

We apply the spectral density reweighting technique to the analysis of the chiral phase transition in finite-temperature lattice quantum chromodynamics (QCD) with four flavors of dynamical staggered fermions and mqa=0.025. Our simulations were performed using the hybrid Monte Carlo method for LtL3 lattices with Lt=4 and L=6, 8 and 10. We calculate partition function zeros, as well as the maxima of the specific heat and of the susceptibilities for the Polyakov loop and for the chiral condensate. A finite size scaling analysis of these data leads to preliminary results for the critical coupling βc, for the critical exponent ν, for the latent heat, and for the jumps in the Polyakov loop and in the chiral condensate.
