Levels of U(1)y in Minimal String Model on Z(N)*Z(M) Orbifolds
H. Kawabe, T. Kobayashi, N. Ohtsubo
We study a minimal string model possessing the same massless spectra as the MSSM on orbifolds. Threshold corrections of the gauge coupling constants of SU(3), SU(2)…
Minimal String Unification and Hidden Sector in Z_8 Orbifold Models
T. Kobayashi
We study the minimal supersymmetric standard model derived from the orbifold models and its hidden sectors. We use a target-space duality anomaly cancellation so as to invest…
Study of Minimal String Unification in Orbifold Models
H. Kawabe, T. Kobayashi, N. Ohtsubo
We study the construction of the minimal supersymmetric standard model from the orbifold models. We use a target-space duality anomaly cancellation and a unification of gauge…
Differential Calculi on h-deformed Bosonic and Fermionic Quantum Planes
Tatsuo Kobayashi
We study differential calculus on h-deformed bosonic and fermionic quantum space. It is shown that the fermionic quantum space involves a parafermionic variable as well as a classi…
Gauge Equivalence in Two--Dimensional Gravity
T. Fujiwara, Y. Igarashi, J. Kubo +1
Two-dimensional quantum gravity is identified as a second-class system which we convert into a first-class system via the Batalin-Fradkin (BF) procedure. Using the extended phase s…
Equivalent models for gauged WZW theory
Haruhiko Terao, Kiyonori Yamada
We modify the WZW theory, which was shown to describe strings in a 2D black hole, to be invariant under chiral gauge symmetry by introducing a Steukelbe…
Unrecognizable Black Holes in Two Dimensions
T. Fujiwara, Y. Igarashi, J. Kubo
The classical 2D cosmological model of Callan, Giddings, Harvey and Strominger possesses a global symmetry that is responsible for decoupling of matter fields. The model is quantiz…
Canonical treatment of two dimensional gravity as an anomalous gauge theory
T. Fujiwara, T. Tabei, Y. Igarashi +2
The extended phase space method of Batalin, Fradkin and Vilkovisky is applied to formulate two dimensional gravity in a general class of gauges. A BRST formulation of the light-con…
