An Improved Single-Plaquette Gauge Action
Debasish Banerjee, Michael Bögli, Kieran Holland +4
We describe and test a nonperturbatively improved single-plaquette lattice action for 4-d SU(2) and SU(3) pure gauge theory, which suppresses large fluctuations of the plaquette, w…
Non-trivial θ-Vacuum Effects in the 2-d O(3) Model
Michael Bögli, Ferenc Niedermayer, Michele Pepe +1
We study θ-vacua in the 2-d lattice O(3) model using the standard action and an optimized constraint action with very small cut-off effects, combined with the geometric topological…
Linear broadening of the confining string in Yang-Mills theory at low temperature
F. Gliozzi, M. Pepe, U. -J. Wiese
The logarithmic broadening predicted by the systematic low-energy effective field theory for the confining string has recently been verified in numerical simulations of (2+1)-d SU(…
Topological Lattice Actions
W. Bietenholz, U. Gerber, M. Pepe +1
We consider lattice field theories with topological actions, which are invariant against small deformations of the fields. Some of these actions have infinite barriers separating d…
The Width of the Color Flux Tube at 2-Loop Order
F. Gliozzi, M. Pepe, U. -J. Wiese
The color flux tube connecting a static quark-anti-quark pair in Yang-Mills theory supports massless transverse fluctuations, which are the Goldstone bosons of spontaneously broken…
The Width of the Confining String in Yang-Mills Theory
F. Gliozzi, M. Pepe, U. -J. Wiese
We investigate the transverse fluctuations of the confining string connecting two static quarks in (2+1)-d SU(2) Yang-Mills theory using Monte Carlo calculations. The exponentially…
