Spectroscopy of SU(4) lattice gauge theory with fermions in the two index anti-symmetric representation
Thomas DeGrand, Yuzhi Liu, Ethan T. Neil +2
We present a study of spectroscopy of SU(4) lattice gauge theory coupled to two flavors of Dirac fermions in the anti-symmetric two index representation. The fermion representation…
Results from lattice simulations of N=4 supersymmetric Yang--Mills
Simon Catterall, Joel Giedt, David Schaich +2
We report recent results and developments from our ongoing lattice studies of supersymmetric Yang--Mills theory. These include a proof that only a single fine-tuni…
Parallel software for lattice N=4 supersymmetric Yang--Mills theory
David Schaich, Thomas DeGrand
We present new parallel software, SUSY LATTICE, for lattice studies of four-dimensional supersymmetric Yang--Mills theory with gauge group SU(N). The lattice actio…
Suppressing dislocations in normalized hypercubic smearing
Thomas DeGrand, Yigal Shamir, Benjamin Svetitsky
Normalized hypercubic smearing improves the behavior of dynamical Wilson-clover fermions, but has the unwanted side effect that it can occasionally produce spikes in the fermion fo…
N=4 Supersymmetry on a Space-Time Lattice
Simon Catterall, Poul H. Damgaard, Thomas DeGrand +2
Maximally supersymmetric Yang--Mills theory in four dimensions can be formulated on a space-time lattice while exactly preserving a single supersymmetry. Here we explore in detail…
The Nc dependencies of baryon masses: Analysis with Lattice QCD and Effective Theory
A. Calle Cordon, T. DeGrand, J. L. Goity
Baryon masses at varying values of Nc and light quark masses are studied with Lattice QCD and the results are analyzed in a low energy effective theory based on a combined framewor…
