Quark number susceptibilities from resummed perturbation theory
We evaluate the second and fourth order quark number susceptibilities in hot QCD using two variations of resummed perturbation theory. On one hand, we carry out a one-loop calculation withinExpand
Equation of state of hot and dense QCD: resummed perturbation theory confronts lattice data
A bstractWe perform a detailed analysis of the predictions of resummed perturbation theory for the pressure and the second-, fourth-, and sixth-order diagonal quark number susceptibilities in a hotExpand
Applications of the Tsallis Statistics in High Energy Collisions
We analytically investigate the thermodynamic variables of a hot and dense system in the framework of the Tsallis non-extensive classical statistics in the massless and in the massive cases. InExpand
Hard-Thermal-Loop QCD thermodynamics and quark number susceptibility
The weak-coupling expansion of the QCD pressure is known up to the order g 6 log g . However, at experimentally relevant temperatures, the corresponding series is poorly convergent. In thisExpand
Phase transitions in finite size systems
We follow recent developments of a finite size thermal field theoretic formalism, which is mainly relevant to the investigation of small size corrections to the thermodynamical properties of theExpand
On the precise determination of the Tsallis parameters in proton - proton collisions at LHC energies
A detailed analysis is presented of the precise values of the Tsallis parameters obtained in $p-p$ collisions for identified particles, pions, kaons and protons at the LHC at three beam energiesExpand
Probing the finite density equation of state of QCD via resummed perturbation theory
In this Ph.D. thesis, the primary goal is to present a recent investigation of the finite density thermodynamics of hot and dense quark-gluon plasma. As we are interested in a temperature regime, inExpand
From Heavy-Ion Collisions to Compact Stars: Equation of State and Relevance of the System Size
In this article, we start by presenting state-of-the-art methods allowing us to compute moments related to the globally conserved baryon number, by means of first principle resummed perturbativeExpand
Kurtoses and high order cumulants: Insights from resummed perturbation theory
Cumulants of conserved charges provide important information about the physics of the quark-gluon plasma around the phase transition region, as they are by construction sensitive to changes in theExpand
Non-extensivity of the QCD pT-spectra
Abstract.We establish a connection between the hadronic distributions, in proton-proton collisions at very high transverse momentum $p_{\mathrm{T}}$pT, obtained via perturbative QCD and the TsallisExpand
