Abstract We compute the large-N limit of the QCD chiral condensate on the lattice using twisted reduced models, and performing controlled continuum and chiral extrapolations. We perform two different calculations: one consists in extracting the chira

Abstract We investigate the role of topology on the lattice determination of the $${\textrm{SU}}(3)$$ SU ( 3 ) strong coupling renormalized via gradient flow. To deal with the topological freezing of standard local algorithms, the definition of the c

Abstract We study, by means of numerical methods, new SU(N) self-dual instanton solutions on R × T 3 with fractional topological charge Q = 1/N. They are obtained on a box with twisted boundary conditions with a very particular choice of twist: both

Abstract In this paper we study the large N limit of four-dimensional Supersymmetric Yang-Mills on the lattice using twisted reduced models. We have generated configurations with dynamical massive gluinos and various lattice ’t Hooft couplings, and

Abstract In this paper we explore a finite volume renormalization scheme that combines three main ingredients: a coupling based on the gradient flow, the use of twisted boundary conditions and a particular asymmetric geometry, that for SU(N) gauge th

Introducción: la falta de conciencia y percepción de riesgo en el hombre han favorecido la existencia de problemas ambientales globales, lo que ha intensificado el calentamiento global y provocado el llamado cambio climático. Objetivo: diseñar un

Abstract We present the result of our computation of the lowest lying meson masses for SU(N) gauge theory in the large N limit (with N f /N → 0). The final values are given in units of the square root of the string tension, and with errors which ac

Abstract We compute the one-loop running of the SU(N) ’t Hooft coupof twelve-flavor SU(3) gauge theoryling in a finite volume gradient flow scheme using twisted boundary conditions. The coupling is defined in terms of the energy density of the grad

Abstract We compute and analyse the low-lying spectrum of 2+1 dimensional SU(N) Yang-Mills theory on a spatial torus of size l × l with twisted boundary conditions. This paper extends our previous work [1]. In that paper we studied the sector with n

Abstract We compute the perturbative expression of Wilson loops up to order g 4 for SU(N ) lattice gauge theories with Wilson action on a finite box with twisted boundary conditions. Our formulas are valid for any dimension and any irreducible twist.
