Nature Of The QCD Transition With Chiral Fermions: Gauss Centre For Supercomputing E.V.

Nature Of The QCD Transition With Chiral Fermions: Gauss Centre For Supercomputing E.V. The nature of the transition was established more than ten years ago in the paper [1] using a technique, called lattice quantum chromodynamics. the computations were done on the state of the art supercomputer of the time, on the pre predecessor of hpc system juqueen at jsc. We discuss properties of thermal quantum chromodynamics obtained by means of lattice simulations with overlap fermions. this fermion discretisation preserves chiral symmetry at finite lattice spacing. we present details of the formulation and results for the chiral observables.

We discuss properties of thermal quantum chromodynamics obtained by means of lattice simulations with overlap fermions. this fermion discretisation preserves chiral symmetry at finite lattice. The nature of the thermal phase transition of two flavor qcd in the chiral limit has an important implication for the qcd phase diagram. we carry out lattice qcd simulations in an attempt to address this problem. In a series of scientific studies using various hpc systems around the world the hotqcd collaboration investigated the transition temperature in qcd. for massive quarks we determined the precise pseudo critical transition temperature: tpc=156.5 mev. Here we show that the phase structure of such strongly interacting matter can be decoded by analysing particle production in high energy nuclear collisions within the framework of statistical.

The nature of the qcd chiral phase transition has been a hot topic in the study of strongly interacting matter for decades. in particular, the phase transition for three degenerate quark flavors in the chiral limit, represented in the lower left corner of the columbia plot, remains unresolved. Transition in transition region as shown in fig. 1 (right). in this case the chiral phase transition may be first order for all values of the chemical potential or, there may exist a critical point such that the transition becomes a crossover. One way to learn more on the behavior of qcd for physical quark masses is to map out the behavior at unphysical up , down and strange quark masses and track structures like critical lines and surfaces at zero, imaginary and real chemical potential.
