  1. 16. Plasma instabilities from hard expanding loops
    Prof. Anton Rebhan (Vienna University of Technology)
    05/11/2016, 11:00

    I will present a review of analytic and numerical results on the evolution of plasma instabilities in an ultrarelativistic, anisotropically expanding plasma in hard loop effective theory.

  2. 32. Finite volume corrections and low momentum cuts in the thermodynamics of quantum gases
    Prof. Kacper Zalewski (Jagiellonian University)

    The ideal boson gas model is used to test the conjecture, proposed in the literature, that the finite volume corrections can be reproduced, with sufficient accuracy, by using the thermodynamic model with the low particle momenta cut off. We find that this is always possible in principle, but simple, convenient formulae are obtained only when the length of the vessel is no less than a few fermi.

  3. 26. The critical behavior of hadronic matter: Comparison of lattice and bootstrap model calculations
    Ludwik Turko (University of Wroclaw (PL))
    05/11/2016, 11:50

    Statistical bootstrap model and the related concept of the limiting temperature begun the discussion about phase transitions in the hadronic matter. This was also the origin of the quark-gluon plazma concept. It is discussed here to which extend lattice studies of QCD critical behavior at non-zero chemical potential are compatible with the statistical bootstrap model calculations.

  4. 7. New vistas in ultraperipheral and peripheral heavy ion collisions
    Antoni Szczurek (Institute of Nuclear Physics)
    05/11/2016, 12:15

    We present calculation of cross sections for diphoton production
    in (semi)exclusive $PbPb$ collisions, relevant for the LHC.
    The calculation is based on equivalent photon approximation in
    the impact parameter space.
    The cross sections for elementary $\gamma \gamma \to \gamma \gamma$
    subprocess are calculated including two different mechanisms.
    We take into account box diagrams
    with...
