    Recent developments at finite density on the lattice

    Gert Aarts (Swansea University)🇬🇧

    Some recent developments to handle the numerical sign problem in QCD and related theories at nonzero density are reviewed. In this contribution I focus on changing the integration order to soften the severity of the sign problem, the density of states, and the extension into the complex plane (complex Langevin dynamics and Lefshetz thimbles).

    Hawking-Unruh hadronization and strangeness production in high energy collisions

    P. Castorina🇮🇹 · H. Satz🇩🇪

    The interpretation of quark ()- antiquark () pairs production and the sequential string breaking as tunneling through the event horizon of colour confinement leads to a thermal hadronic spectrum with a universal Unruh temperature, Mev,related to the quark acceleration, , by . The resulting temperature depends on the quark mass and then on the content of the produced hadrons, causing a deviation from full equilibrium and hence a suppression of strange particle production in elementary collisions. In nucleus-nucleus collisions, where the quark density is much bigger, one has to introduce an average temperature (acceleration) which dilutes the quark mass effect and the strangeness suppression almost disappears.
