Leibniz rule and exact supersymmetry on lattice: a case of supersymmetrical quantum mechanics
Mitsuhiro Kato, Makoto Sakamoto, Hiroto So
We propose a new formulation of lattice theory. It is given by a matrix form and suitable for satisfying Leibniz rule on lattice. The theory may be interpreted as a multi-flavor sy…
Gauge Symmetry Breaking with a Large Mass Hierarchy
Tomoaki Nagasawa, Makoto Sakamoto
We propose a higher dimensional scenario to solve the gauge hierarchy problem. In our formulation, a crucial observation is that a supersymmetric structure is hidden in the 4d spec…
Symmetry Breaking/Restoration in a Non-Simply Connected Space-Time
Hisaki Hatanaka, Seiho Matsumoto, Katsuhiko Ohnishi +1
Field theories compactified on non-simply connected spaces, which in general allow to impose twisted boundary conditions, are found to unexpectedly have a rich phase structure. One…
Peculiarity of String Theory on Orbifolds in the Presence of an Antisymmetric Background Field
Makoto Sakamoto
We study string theory on orbifolds in the presence of an antisymmetric constant background field and discuss some of new aspects of the theory. It is shown that the term with the…
