The quenched glueball spectrum from smeared spectral densities
Marco Panero, Antonio Smecca, Nazario Tantalo +1
The standard approach to compute the glueball spectrum on the lattice relies on the evaluation of effective masses from two-point correlation functions of operators with the quantu…
Conformal field theory and the hot phase of three-dimensional U(1) gauge theory
Michele Caselle, Alessandro Nada, Marco Panero +1
We study the high-temperature phase of compact U(1) gauge theory in 2+1 dimensions, comparing the results of lattice calculations with analytical predictions from the conformal-fie…
Equivalence of Meson Scattering Amplitudes in Strong Coupling Lattice and Flat Space String Theory
Adi Armoni, Edwin Ireson, Davide Vadacchino
We consider meson scattering in the framework of the lattice strong coupling expansion. In particular we derive an expression for the 4-point function of meson operators in the pla…
Squared width and profile of the confining flux tube in the U(1) LGT in 3D
Michele Caselle, Marco Panero, Davide Vadacchino
The dual formulation of the compact U(1) lattice gauge theory in three spacetime dimensions allows to finely study the squared width and the profile of the confining flux tube on a…
Width of the flux tube in compact U(1) gauge theory in three dimensions
Michele Caselle, Marco Panero, Davide Vadacchino
We study the squared width and the profile of flux tubes in compact U(1) lattice gauge theory in three spacetime dimensions. The results obtained from numerical calculations in the…
Effective string description of the interquark potential in the 3D U(1) lattice gauge theory
Davide Vadacchino, Michele Caselle, Marco Panero +1
The U(1) lattice gauge theory in three dimensions is a perfect laboratory to study the properties of the confining string. On the one hand, thanks to the mapping to a Coulomb gas o…
On the rigid string contribution to the interquark potential
Michele Caselle, Davide Vadacchino, Marco Panero +1
Owing to Lorentz invariance, the leading terms in the effective action describing the low-energy dynamics of flux tubes in a confining gauge theory are universal. Besides the terms…
A different kind of string
Michele Caselle, Marco Panero, Roberto Pellegrini +1
In U(1) lattice gauge theory in three spacetime dimensions, the problem of confinement can be studied analytically in a semi-classical approach, in terms of a gas of monopoles with…
Fine structure of the confining string in an analytically solvable 3D model
Davide Vadacchino, Michele Caselle, Roberto Pellegrini +1
In lattice gauge theory in three spacetime dimensions, confinement can be analytically shown to persist at all values of the coupling. Furthermore, the explicit pre…
