Integrable structures in LGTs near the deconfinement transition
M. Caselle, G. Delfino, P. Giudice +4
In this contribution we review some recent results about the emergence of 2D integrable systems in 3D Lattice Gauge Theories near the deconfinement transition. We focus on some con…
Excited-Nucleon Spectroscopy with 2+1 Fermion Flavors
Saul Cohen, John M. Bulava, Justin Foley +10
We present progress made by the Hadron Spectrum Collaboration (HSC) in determining the tower of excited nucleon states using 2+1-flavor anisotropic clover lattices. The HSC has bee…
An anisotropic preconditioning for the Wilson fermion matrix on the lattice
Balint Joo, Robert G. Edwards, Michael J. Peardon
A preconditioning for the Wilson fermion matrix on the lattice is defined which is particularly suited to the case when the temporal lattice spacing is much smaller than the spatia…
Exploring the Spectrum of QCD using the Lattice
John Bulava, Saul Cohen, Jozef Dudek +14
The calculation of the spectrum of QCD is key to an understanding of the strong interactions, and vital if we are to capitalize on the experimental study of the spectrum. In this p…
A novel quark-field creation operator construction for hadronic physics in lattice QCD
Michael Peardon, John Bulava, Justin Foley +7
A new quark-field smearing algorithm is defined which enables efficient calculations of a broad range of hadron correlation functions. The technique applies a low-rank operator to…
The confining string beyond the free-string approximation in the gauge dual of percolation
Pietro Giudice, Ferdinando Gliozzi, Stefano Lottini
We simulate five different systems belonging to the universality class of the gauge dual of three-dimensional random percolation to study the underlying effective string theory at…
