The paper

Original abstract

The quark degrees of freedom of the QGP with special focus on mass effects are investigated. A next-to-leading-order perturbation theory approach with quark mass dependence is applied and compared to lattice QCD results.

Besides the established calculations of the Charm fluctuations on the lattice, we use a perturbative framework including bare quark mass dependence at next-to-leading order, presented in Refs. [ref] , to calculate the first results for second and fourth order Charm quark susceptibilities and their ratio with weak coupling techniques.

As in Ref. [ref] we choose $α_s(Λ)=4π/β_0L[1-2β_1/β_0^2lnL/L]$, with $Λ$ being the renormalization scale and $L=2ln(Λ/Λ_MS)$, $β_0=11-2N_f/3$ and $β_1=51-19N_f/3$.

Requiring $m_s=93.6$ at $Λ=2$ GeV [ref] for the strange quark mass, leads to $m̂_s=252$ MeV.

We start with the ratio of the strange- over up-quark susceptibility of second order that is depicted in Fig. [ref] (a) and compared with lattice data of Ref. [ref] .

The free energy of hot QCD can in fact be separated into contributions from momentum scales $T$, $gT$ and $g^2T$ [ref] , that are called hard, soft and supersoft modes.

The experiments at the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory as well as at the Large Hadron Collider (LHC) in Geneva showed clear evidences for the creation of a novel state of matter that is usually refered to as Quark-Gluon-Plasma (QGP) (see e.g. Ref. [ref] for a recent review).
