High-Temperature QCD: theory overview

Massimo D'Elia

We review the recent progress achieved in the theoretical investigation of Quantum Chromodynamics in the high temperature regime, with a focus on results achieved by lattice QCD si…

QCD phase diagram in a magnetic background for different values of the pion mass

Massimo D'Elia, Floriano Manigrasso, Francesco Negro +1

We investigate the behavior of the pseudo-critical temperature of $N_{f} = 2 + 1$ QCD as a function of a static magnetic background field for different values of the pion mass, going u…

Finite density 2d O(3) sigma model: dualization and numerical simulations

B. Alles, O. Borisenko, Alessandro Papa

The action of the 2d O(3) non-linear sigma model on the lattice in a bath of particles, when expressed in terms of standard O(3) degrees of freedom, is complex. A reformulation of…

Topological properties of $C P^{N - 1}$ models in the large- $N$ limit

Claudio Bonanno, Claudio Bonati, Massimo D'Elia

We investigate, by numerical simulations on a lattice, the $θ$ -dependence of 2 $d$ $C P^{N - 1}$ models for a range of $N$ going from 9 to 31, combining imaginary $θ$ and simulated tem…

The curvature of the chiral pseudocritical line from LQCD: analytic continuation and Taylor expansion compared

Claudio Bonati, Massimo D'Elia, Francesco Negro +2

We present a determination of the curvature $κ$ of the chiral pseudocritical line from $N_{f} = 2 + 1$ lattice QCD at the physical point obtained by adopting the Taylor expansion approac…

Roberge-Weiss endpoint and chiral symmetry restoration in $N_{f} = 2 + 1$ QCD

Claudio Bonati, Enrico Calore, Massimo D'Elia +6

We investigate the fate of the Roberge-Weiss endpoint transition and its connection with the restoration of chiral symmetry as the chiral limit of $N_{f} = 2 + 1$ QCD is approached. We…

Topology in full QCD at high temperature: a multicanonical approach

Claudio Bonati, Massimo D'Elia, Guido Martinelli +3

We investigate the topological properties of $N_{f} = 2 + 1$ QCD with physical quark masses, at temperatures around 500 MeV. With the aim of obtaining a reliable sampling of topologica…

$θ$ dependence in trace deformed $S U (3)$ Yang-Mills theory: a lattice study

Claudio Bonati, Marco Cardinali, Massimo D'Elia

In this paper we investigate, by means of numerical lattice simulations, the topological properties of the trace deformed $S U (3)$ Yang-Mills theory defined on $S_1\times\mathbb{R}^…

Effects of a strong magnetic field on the QCD flux tube

Claudio Bonati, Salvatore Calì, Massimo D'Elia +4

In this work we investigate the effect of an external magnetic field B on the shape of flux tubes in QCD by means of lattice simulations, performed with N_f=2+1 flavors of stout im…

Anomalous finite-size scaling at thermal first-order transitions in systems with disordered boundary conditions

Haralambos Panagopoulos, Andrea Pelissetto, Ettore Vicari

We investigate the equilibrium and off-equilibrium behaviors of systems at thermal first-order transitions (FOTs) when the boundary conditions favor one of the two phases. As a the…

Curvature of the pseudocritical line in QCD: Taylor expansion matches analytic continuation

Claudio Bonati, Massimo D'Elia, Francesco Negro +2

We determine the curvature of the pseudo-critical line of $N_{f} = 2 + 1$ QCD with physical quark masses via Taylor expansion in the quark chemical potentials. We adopt a discretizat…
