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…
Canonical Equivalence between Super D-string and Type IIB Superstring
Yuji Igarashi, Katsumi Itoh, Kiyoshi Kamimura +1
We show that the super D-string action is canonically equivalent to the type IIB superstring action with a world-sheet gauge field. Canonical transformation to the type IIB theory…
A Rule of Thumb Derivation of Born-Infeld Action for D-branes
Rika Endo, Rie Kuriki, Shin'ichi Nojiri +1
A rule of thumb derivation of the Dirac-Born-Infeld action for D-branes is studied à la Fradkin and Tseytlin, by simply integrating out of the superstring coordinates in a narrow s…
BRST Cohomology and Renormalizability of Quantum Gravity near Two Dimensions
Yoshihisa Kitazawa, Rie Kuriki, Katsumi Shigura
We discuss the renormalizability of quantum gravity near two dimensions based on the results obtained by a computation of the BRST-antibracket cohomology in the space of local func…
The WZ Term of the Spinning String and its On-shell Structure
J. Gomis, K. Kamimura, R. Kuriki
The Wess-Zumino term of the spinning string is constructed in terms of their anomalies using an extended field-antifield formalism. A new feature appears from a fact that the non-a…
New insight into BRST anomalies in superstring theory
T. Fujiwara, Y. Igarashi, M. Koseki +2
Based on the extended BRST formalism of Batalin, Fradkin and Vilkovisky, we perform a general algebraic analysis of the BRST anomalies in superstring theory of Neveu-Schwarz-Ramond…
