Reconfinement, localization and thermal monopoles in $S U (3)$ trace-deformed Yang-Mills theory

Claudio Bonati, Marco Cardinali, Massimo D'Elia +2

We study, by means of numerical lattice simulations, the properties of the reconfinement phase transition taking place in trace deformed $S U (3)$ Yang-Mills theory defined on $\math…

Large- $N$ $S U (N)$ Yang-Mills theories with milder topological freezing

Claudio Bonanno, Claudio Bonati, Massimo D'Elia

We simulate $4 d$ $S U (N)$ pure-gauge theories at large $N$ using a parallel tempering scheme that combines simulations with open and periodic boundary conditions, implementing the a…

Neutron electric dipole moment using lattice QCD simulations at the physical point

C. Alexandrou, A. Athenodorou, K. Hadjiyiannakou +1

We extract the neutron electric dipole moment $∣ d_{N} ∣$ within the lattice QCD formalism. We analyse one ensemble of $N_{f} = 2 + 1 + 1$ twisted mass clover-improved fermions…

Compact Gauge Fields on Causal Dynamical Triangulations: a 2D case study

Alessandro Candido, Giuseppe Clemente, Massimo D'Elia +1

We discuss the discretization of Yang-Mills theories on Dynamical Triangulations in the compact formulation, with gauge fields living on the links of the dual graph associated with…

Glueballs and Strings in $S p (2 N)$ Yang-Mills theories

Ed Bennett, Jack Holligan, Deog Ki Hong +5

Motivated in part by the pseudo-Nambu Goldstone Boson mechanism of electroweak symmetry breaking in Composite Higgs Models, in part by dark matter scenarios with strongly coupled o…

Berezinskii-Kosterlitz-Thouless transitions in two-dimensional lattice SO( $N_{c}$ ) gauge theories with two scalar flavors

Claudio Bonati, Alessio Franchi, Andrea Pelissetto +1

We study the phase diagram and critical behavior of a two-dimensional lattice SO( $N_{c}$ ) gauge theory ( $N_{c} \geq 3$ ) with two scalar flavors, obtained by partially gauging a maximall…

Spectral Analysis of Causal Dynamical Triangulations via Finite Element Method

Fabio Caceffo, Giuseppe Clemente

We examine the dual graph representation of simplicial manifolds in Causal Dynamical Triangulations (CDT) as a mean to build observables, and propose a new representation based on…

A gauge invariant order parameter for monopole condensation in $QC D$ vacuum

Adriano Di Giacomo

In this paper we improve the existing order parameter for monopole condensation in gauge theory vacuum, making it gauge-invariant from scratch and free of the spurious infrared pro…

Spectrum of Trace Deformed Yang-Mills Theories

Andreas Athenodorou, Marco Cardinali, Massimo D'Elia

In this paper we study, by means of numerical simulations, the behaviour of the scalar glueball mass and the ground state of the torelon for trace deformed Yang-Mills theory define…

$θ$ -dependence in the small- $N$ limit of $2 d$ $C P^{N - 1}$ models

Mario Berni, Claudio Bonanno, Massimo D'Elia

We present a systematic numerical study of $θ$ -dependence around $θ = 0$ in the small- $N$ limit of $2 d$ $C P^{N - 1}$ models, aimed at clarifying the possible presence of a divergent to…

The glueball spectrum of SU(3) gauge theory in 3+1 dimension

Andreas Athenodorou, Michael Teper

We calculate the low-lying glueball spectrum of the SU(3) lattice gauge theory in 3+1 dimensions for the range of beta up to beta=6.50 using the standard plaquette action. We do so…

Universal low-temperature behavior of two-dimensional lattice scalar chromodynamics

Claudio Bonati, Andrea Pelissetto, Ettore Vicari

We study the role that global and local nonabelian symmetries play in two-dimensional lattice gauge theories with multicomponent scalar fields. We start from a maximally O( $M$ )-sym…
