    Title: Properties of hadronic systems according to the non-extensive self-consistent thermodynamics
    Author: Deppman, Airton
    Subject: High Energy Physics - Phenomenology ; Nuclear Theory
    Description: The non-extensive self-consistent theory describing the thermodynamics of hadronic systems at high temperatures is used to derive some thermodynamical quantities, as pressure, entropy, speed of sound and trace-anomaly. The calculations are free of fitting parameters, and the results are compared to lattice QCD calculations, showing a good agreement between theory and data up to temperatures around 175 MeV. Above this temperature the effects of a singularity in the partition function at To = 192 MeV results in a divergent behaviour in respect with the lattice calculation. Comment: 10 pages, 7 figures, text modified in a few aspects. The discussion on the connections between non-extensive and lattice quantities is modified by the inclusion of a new figure

    Title: Renormalization group equation for Tsallis statistics
    Author: Deppman, Airton
    Contributor: Deppman, Airton (pacrepositoryorg)
    Subject: Fireballs ; Quantum Chromodynamics ; Statistics
    Description: The non extensive statistics proposed by C. Tsallis has found wide applicability, being present even in the description of experimental data from high energy collisions. A system with a fractal structure in its energy-momentum space, named thermofractal, was shown to be described thermodynamically by the non extensive statistics. Due to the many common features between thermofractals and Hagedorn's fireballs, this system offers the possibility to investigate the origins of non extensivity in hadronic physics and in QCD. In this regard, the investigation of the scaling properties of thermofractals through the renormalization group equation, known as Callan-Symanzik equation, can be an interesting approach.
