Phase diagram of QCD in a magnetic background

Massimo D'Elia, Lorenzo Maio, Francesco Sanfilippo +1

We provide numerical evidence that the thermal QCD crossover turns into a first order transition in the presence of large enough magnetic background fields. The critical endpoint i…

Localization properties of Dirac modes at the Roberge-Weiss phase transition

Marco Cardinali, Massimo D'Elia, Francesco Garosi +1

We study the localization properties of the low-lying Dirac eigenmodes in QCD at imaginary chemical potential $μ^_{I} = π$ at temperatures above the Roberge-Weiss transition tempera…

Confining and chiral properties of QCD in extremely strong magnetic fields

Massimo D'Elia, Lorenzo Maio, Francesco Sanfilippo +1

We investigate, by numerical lattice simulations, the static quark-antiquark potential, the flux tube properties and the chiral condensate for $N_{f} = 2 + 1$ QCD with physical quark m…

Three-dimensional lattice SU( $N_{c}$ ) gauge theories with multiflavor scalar fields in the adjoint representation

Claudio Bonati, Alessio Franchi, Andrea Pelissetto +1

We consider three-dimensional lattice SU( $N_{c}$ ) gauge theories with multiflavor ( $N_{f} > 1$ ) scalar fields in the adjoint representation. We investigate their phase diagram, identify…

Lattice gauge theories in the presence of a linear gauge-symmetry breaking

Claudio Bonati, Andrea Pelissetto, Ettore Vicari

We study the effects of gauge-symmetry breaking (GSB) perturbations in three-dimensional lattice gauge theories with scalar fields. We study this issue at transitions in which gaug…

The unreasonable effectiveness of effective string theory: the case of the 3d SU(2) Higgs model

Claudio Bonati, Michele Caselle, Silvia Morlacchi

We study string breaking in the three dimensional SU(2) Higgs model, using values of the gauge coupling for which the confinement-like and Higgs-like regions of the phase diagram a…

SU(N) gauge theories in 3+1 dimensions: glueball spectrum, string tensions and topology

Andreas Athenodorou, Michael Teper

We calculate the low-lying glueball spectrum, some string tensions and some properties of topology and the running coupling for SU(N) lattice gauge theories in 3+1 dimensions. We d…

Constraints for the semileptonic $B \to D^{(*)}$ form factors from lattice QCD simulations of two-point correlation functions

G. Martinelli, S. Simula, L. Vittorio

In this work we present the first non-perturbative determination of the hadronic susceptibilities that constrain the form factors entering the semileptonic $B \to D^{(*)} \ell ν_\e…

Unitarity Bounds for Semileptonic Decays in Lattice QCD

M. Di Carlo, G. Martinelli, M. Naviglio +3

In this work we discuss in detail the non-perturbative determination of the momentum dependence of the form factors entering in semileptonic decays using unitarity and analyticity…

Breaking of the gauge symmetry in lattice gauge theories

Claudio Bonati, Andrea Pelissetto, Ettore Vicari

We study perturbations that break gauge symmetries in lattice gauge theories. As a paradigmatic model, we consider the three-dimensional Abelian-Higgs (AH) model with an N-componen…

Two-dimensional lattice SU( $N_{c}$ ) gauge theories with multiflavor adjoint scalar fields

Claudio Bonati, Alessio Franchi, Andrea Pelissetto +1

We consider two-dimensional lattice SU( $N_{c}$ ) gauge theories with $N_{f}$ real scalar fields transforming in the adjoint representation of the gauge group and with a global O( $N_{f}$ )…

Investigating the conformal behaviour of SU(2) with one adjoint Dirac flavor

Andreas Athenodorou, Ed Bennett, Georg Bergner +1

We present a major update on our investigations of SU(2) gauge theory with one Dirac flavor in the adjoint representation on the lattice. In particular we consider larger volumes,…
