Lattice Tests of Supersymmetric Yang-Mills Theory?
Nick Evans, Steve Hsu, Myck Schwetz
Supersymmetric Yang Mills theory is directly accessible to lattice simulations using current methodology, and can provide a non-trivial check of recent exact results in SQCD. In or…
QCD at Large Angle and Axion Cosmology
N. Evans, S. D. H. Hsu, A. Nyffeler +1
We use the chiral Lagrangian to investigate the global properties of the -flavor QCD vacuum as a function of the parameter. In the case of exact quark degeneracy we find evi…
Phase Transitions in Softly Broken N=2 SQCD at Non-zero Theta Angle
N. Evans, S. D. H. Hsu, M. Schwetz
We investigate the behavior of softly broken SQCD at non-zero bare theta angle , using superfield spurions to implement the SUSY breaking. We find a first-order phase tr…
Chiral Perturbation Theory, Large-N_c and the eta' Mass
N. Evans, S. D. H. Hsu, M. Schwetz
Using chiral perturbation theory and the large- expansion, we obtain expressions for the mass and mixing in terms of low-energy chiral Lagrangian parameters. This…
