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…
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…
Comments on D-Instantons in c<1 Strings
Masafumi Fukuma, Shigeaki Yahikozawa
We suggest that the boundary cosmological constant ζin c<1 unitary string theory be regarded as the one-dimensional complex coordinate of the target space on which the boundaries o…
