Low Energy Action of "Covariant" Superstring Field Theory in the NS-NS pp-Wave Background
Yoichi Chizaki, Shigeaki Yahikozawa
Exact construction of superstring field theory in some background fields is very important. We construct the low energy NS-NS sector of superstring field action in the pp-wave back…
General Operator Solutions and BRST Quantization of Superstrings in the pp-Wave with Torsion
Yoichi Chizaki, Shigeaki Yahikozawa
We completely accomplish the canonically covariant quantization of Ramond-Neveu-Schwarz (RNS) superstrings in the pp-wave background with a non-zero flux of the NS-NS antisymmetric…
Covariant BRST Quantization of Closed Strings in the PP-Wave Background
Yoichi Chizaki, Shigeaki Yahikozawa
We canonically quantize closed string theory in the pp-wave background with a non-zero flux of the three-form field strength by using the covariant BRST operator formalism. In this…
Information Metric on Instanton Moduli Spaces in Nonlinear Sigma Models
Shigeaki Yahikozawa
We study the information metric on instanton moduli spaces in two-dimensional nonlinear sigma models. In the CP^1 model, the information metric on the moduli space of one instanton…
The stability of the shell of D6-D2 branes in a supergravity solution
K. Maeda, T. Torii, M. Narita +1
The stability of the shell of wrapped D6-branes on K3 is investigated from the point of view of supergravity. We first construct an effective energy-momentum tensor for the shell u…
The excitation of a charged string passing through a shock wave in a charged Aichelburg-Sexl spacetime
Kengo Maeda, Takashi Torii, Makoto Narita +1
We investigate how much a first-quantized charged bosonic test string gets excited after crossing a shock wave generated by a charged particle with mass and charge $\ti…
