Numerical simulation based on lattice regularization is a powerful non-perturbative tool for the quantum field theory. Thanks to recent developments in formulation, now simulation of supersymmetric gauge theory is possible. In this seminar, I will present some results for 2-dimensional N=(2,2) super Yang-Mills theory. First we confirm that the supersymmetry, which is broken at finite lattice spacing, is in fact realized in the continuum limit. And then we measure the vacuum energy, which is important to observe spontaneous SUSY breaking if any in this system. We also show some results in large-N.
The Particle Physics Theory seminar is a weekly series of talks reflecting the diverse interests of the group. Topics include analytic and numerical calculations based on the Standard Model of elementary particle physics, theories exploring new physics, as well as more formal developments in gauge theories and gravity..
