Observing dynamical SUSY breaking with lattice simulation (2008)
On the basis of the recently developed lattice formulation of supersymmetric theories which keeps a part of the supersymmetry, we propose a method of observing dynamical SUSY breaking with lattice...
RHMC simulation of two-dimensional N=(2,2) super Yang-Mills with exact supersymmetry (2008)
We report our numerical simulation of two-dimensional N=(2,2) super Yang-Mills. The lattice model we use is one proposed by F.Sugino which keeps one exact supersymmetry at finite lattice spacing. We...
Observing dynamical supersymmetry breaking with euclidean lattice simulations (2007)
Kanamori, Issaku, Sugino, Fumihiko, Suzuki, Hiroshi
A strict positivity of the ground-state energy is a necessary and sufficient condition for spontaneous supersymmetry breaking. This ground-state energy may be directly determined from the expectation...

Kanamori, Issaku, Sugino, Fumihiko, Suzuki, Hiroshi
The global supersymmetry is spontaneously broken if and only if the ground-state energy is strictly positive. We propose to use this fact to observe the spontaneous supersymmetry breaking in...
