Analysis of regulator and cutoff artifacts in the phase diagram of the quark-meson model
Jonas Stoll, Niklas Zorbach, Lutz Kiefer +3
We study regulator and cutoff artifacts in the quark-meson model at finite temperature and quark chemical potential within the functional renormalization-group approach using the l…
Elliptic flow of charm quarks produced in the early stage of pA collisions
Gabriele Parisi, Fabrizio Murgana, Vincenzo Greco +1
We investigate the build-up of elliptic flow of charm quarks produced in the early pre-equilibrium stage of high-energy proton--nucleus collisions. The initial stage is modeled wit…
Assessing the Reconstruction of the Critical Line in the QCD Phase Diagram from Imaginary to Real Chemical Potential
Fabrizio Murgana, Marco Ruggieri
We test a technique adopted in the lattice simulations framework, to reconstruct the chiral-phase boundary at real chemical potential, , via extrapolation from imaginary . We…
Topological Susceptibility in the Superconductive Phases of Quantum Chromodynamics: a Dyson-Schwinger Perspective
Fabrizio Murgana, Giorgio Comitini, Marco Ruggieri
We test non-perturbative gluon propagators recently studied in the literature, by computing the topological susceptibility, , of the superconductive phases of Quantum Chromodyna…
Functional Renormalization Group analysis of the quark-condensation pattern on the Fermi surface: A simple effective-model approach
Kie Sang Jeong, Fabrizio Murgana, Ashutosh Dash +1
A simple effective model for the intermediate-density regime is constructed from the high-density effective theory of quantum chromodynamics (QCD). In the effective model, under a…
Topological susceptibility and axion potential in two-flavor superconductive quark matter
Fabrizio Murgana, David E. Alvarez Castillo, Ana G. Grunfeld +1
We study the potential of the axion, , of Quantum Chromodynamics, in the two-flavor color superconducting phase of cold and dense quark matter. We adopt a Nambu-Jona-Lasinio-lik…
Functional Renormalization Group Study of Thermodynamic Geometry Around the Phase Transition of Quantum Chromodynamic
Fabrizio Murgana, Vincenzo Greco, Marco Ruggieri +1
We investigate the thermodynamic geometry of the quark-meson model at finite temperature, , and quark number chemical potential, . We extend previous works by the inclusion o…
Reanalysis of critical exponents for the O(N) model via a hydrodynamic approach to the Functional Renormalization Group
Fabrizio Murgana, Adrian Koenigstein, Dirk H. Rischke
We compute the critical exponents of the O(N) model within the Functional Renormalization Group (FRG) approach. We use recent advances which are based on the observation that the F…
