High Energy Behavior of Wilson Lines
A. Dhar, Y. Kitazawa
We investigate the high energy behavior of the correlation functions of the open Wilson lines in noncommutative gauge theory. We obtain a very simple physical picture that they are…
Gaussian and Mean Field Approximations for Reduced Yang-Mills Integrals
Satsuki Oda, Fumihiko Sugino
In this paper, we consider bosonic reduced Yang-Mills integrals by using some approximation schemes, which are a kind of mean field approximation called Gaussian approximation and…
Noncommutative Tachyon from Background Independent Open String Field Theory
Kazumi Okuyama
We analyze the tachyon field in the bosonic open string theory in a constant B-field background using the background independent open string field theory. We show that in the large…
Symmetry Origin of Nonlinear Monopole
Koji Hashimoto, Takayuki Hirayama, Sanefumi Moriyama
We revisit the non-linear BPS equation: the Dirac monopole of the Born-Infeld theory in the B-field background. The rotation used in our previous papers to discuss the scalar field…
Topological Charge of U(1) Instantons
Furuuchi Kazuyuki
Non-singular instantons are shown to exist on noncommutative R^4 even with a U(1) gauge group. Their existence is primarily due to the noncommutativity of the space. The relation b…
Wilson loops in strongly coupled noncommutative gauge theories
A. Dhar, Y. Kitazawa
We discuss Wilson loop averages in 4-dimensional non-commutative superYang-Mills theory using the dual supergravity description. We postulate that the Wilson loops are located at t…
Open Superstring Theory and Superalgebra of the Brane Antibrane System
Machiko Hatsuda, Makoto Sakaguchi
Open superstring theory is formulated in terms of a nondegenerate supertranslation algebra. A supercharge for a tachyonic superstring can be also defined classically by taking into…
Dp-D(p+4) in Noncommutative Yang-Mills
Kazuyuki Furuuchi
An anti-self-dual instanton solution in Yang-Mills theory on noncommutative with an anti-self-dual noncommutative parameter is constructed. The solution is constructed by…
U-duality Between NCOS Theory and Matrix Theory
Seungjoon Hyun
We show that the NCOS (noncommutative open string) theories on torus () are U-dual to matrix theory on torus with electric flux background. Under U-duality, the numb…
Boundary States in B-Field Background
Kazumi Okuyama
We consider the boundary states which describe D-branes in a constant B-field background. We show that the two-form field Phi, which interpolates commutative and noncommutative des…
Free Field Appoach to String Theory on AdS_3
Kazuo Hosomichi, Kazumi Okuyama, Yuji Satoh
We discuss the correlation functions of the SL(2,C)/SU(2) WZW model, or the CFT on the Euclidean AdS_3. We argue that their calculation is reduced to that of a free theory by takin…
Nondegenerate Super-Anti-de Sitter Algebra and a Superstring Action
Machiko Hatsuda, Kiyoshi Kamimura, Makoto Sakaguchi
We construct an Anti-de Sitter(AdS) algebra in a nondegenerate superspace. Based on this algebra we construct a covariant kappa-symmetric superstring action, and we examine its dyn…
Symmetrization of the Berezin Star Product and Multiple Star Product Method
Kazunori Wakatsuki
We construct a multiple star product method and by using this method, show that integral forms of some star products can be written in terms of the path-integral. This method can b…
Equivalence of Projections as Gauge Equivalence on Noncommutative Space
Kazuyuki Furuuchi
Projections play crucial roles in the ADHM construction on noncommutative . In this article a framework for the description of equivalence relations between projections is pr…
Instantons, Monopoles and the Flux Quantization in the Faddeev-Niemi Decomposition
Toyohiro Tsurumaru, Izumi Tsutsui, Akira Fujii
We study how instantons arise in the low energy effective theory of the SU(2) Yang-Mills theory in the context of the non-linear sigma model recently propose by Faddeev and Niemi.…
String Scale in Noncommutative Yang-Mills
N. Ishibashi, S. Iso, H. Kawai +1
We identify the effective string scale of noncommutative Yang-Mills theory (NCYM) with the noncommutativity scale through its dual supergravity description. We argue that Newton's…
Chamseddine, Fröhlich, Grandjean Metric and Localized Higgs Coupling on Noncommutative Geometry
R. Kuriki, A. Sugamoto
We propose a geometrized Higgs mechanism based on the gravitational sector in the Connes-Lott formulation of the standard model, which has been constructed by Chamseddine, Fr$\ddot…

Ken-ji Hamada
In this note we give some remarks on the BRST formulation of a renormalizable and diffemorphism invariant 4D quantum gravity recently proposed by the author, which satisfies the in…
Numerical Analysis of the Double Scaling Limit in the IIB Matrix Model
S. Horata, H. S. Egawa
The bosonic IIB matrix model is studied using a numerical method. This model contains the bosonic part of the IIB matrix model conjectured to be a non-perturbative definition of th…
Path Integral Approach to String Theory on AdS_3
Nobuyuki Ishibashi, Kazumi Okuyama, Yuji Satoh
Using the path integral approach, we discuss the correlation functions of the $SL(2,\bfC)/SU(2)$ WZW model, which corresponds to the string theory on the Euclidean . We obta…
The no-ghost theorem for string theory in curved backgrounds with a flat timelike direction
Masako Asano, Makoto Natsuume
It is well-known that the standard no-ghost theorem can be extended straightforwardly to the general c=26 CFT on R^{d-1,1} \times K, where 2 \leq d \leq 26 and K is a compact unita…
