U(N) Gauge Model and Partial Breaking of N=2 Supersymmetry
Kazuhito Fujiwara, Hiroshi Itoyama, Makoto Sakaguchi
We briefly review a construction of N=2 supersymmetric U(N) gauge model in which rigid N=2 supersymmetry is spontaneously broken to N=1. This model generalizes the abelian model co…
D-branes of Covariant AdS Superstrings -- An Overview --
Makoto Sakaguchi, Kentaroh Yoshida
We briefly review a covariant analysis of D-branes of type IIB superstring on the AdS_5xS^5 background from the κ-invariance of the Green-Schwarz string action. The possible config…
IIB PP-Waves with Extra Supersymmetries
Makoto Sakaguchi
We examine Killing spinor equations of the general IIB pp-wave backgrounds, which contain a scalar H(x^m,x^-) in the metric and a self-dual four-form ξ(x^m,x^-) in the self-dual fi…
Pregeometrical Formulation of Berkovits' Open RNS Superstring Field Theories
Makoto Sakaguchi
We propose a pregeometrical formulation of Berkovits' open Ramond-Neveu-Schwarz (RNS) superstring field theories. We show that Berkovits' open RNS superstring field theories arise…
