Supersymmetry on the lattice
Alessandra Feo
Lattice results in supersymmetry are summarized. Past, present and future perspectives are discussed.
Remark on the Theoretical Uncertainty in - Mixing
Sinead M. Ryan, Andreas S. Kronfeld
We re-examine the theoretical uncertainty in the Standard Model expression for - mixing. We focus on lattice calculations of the ratio , needed to relate the osc…
SO(3) Yang-Mills theory on the lattice
A. Barresi, G. Burgio, M. Muller-Preussker
We numerically investigate the phase structure of pure SO(3) LGT at zero and non-zero temperature in the presence of a Z2 blind monopole chemical potential. The physical meaning of…
Multiple molecular dynamics time-scales in Hybrid Monte Carlo fermion simulations
Mike Peardon, James Sexton
A scheme for separating the high- and low-frequency molecular dynamics modes in Hybrid Monte Carlo (HMC) simulations of gauge theories with dynamical fermions is presented. The alg…
QCD on 2+2 anisotropic lattices
G. Burgio, A. Feo, M. J. Peardon +1
We discuss the implementation of QCD on 2+2 anisotropic lattices. Technical details regarding the choice of the action as well as perturbative and non-perturbative improvement are…
A Hamiltonian lattice study of the two-dimensional Wess-Zumino model
Matteo Beccaria, Massimo Campostrini, Alessandra Feo
We investigate a Hamiltonian lattice version of the two-dimensional Wess-Zumino model by Quantum Monte Carlo simulations. In order to study the pattern of supersymmetry breaking, w…
