NSR Open Super-string in the proper-time gauge I: Free Field Theory
Taejin Lee
We study the Neveu-Schwarz-Ramond (NSR) open super-string theory in the proper-time gauge. The string field action is obtained by evaluating the Polyakov string path integral. In t…
BRST Ghost-Vertex Operator in Witten's Cubic Open String Field Theory on Multiple -branes
Taejin Lee
The Becchi-Rouet-Stora-Tyutin (BRST) ghost field is a key element in constructing Witten's cubic open string field theory. However, to date, the ghost sector of the string field th…
Witten's Cubic Open String Field Theory on multiple -branes
Taejin Lee
We study Witten's cubic open string field theory on multiple -branes. On multiple -branes the string fields carry group indices. Mapping the string world-sheet onto…
Canonical Quantization of Massive Symmetric Rank-Two Tensor in String Theory
Hayun Park, Taejin Lee
The canonical quantization of a massive symmetric rank-two tensor in string theory, which contains two Stueckelberg fields, was studied. As a preliminary study, we performed a cano…
Four-Gauge-Particle Scattering Amplitudes and Polyakov String Path Integral in the proper-time gauge
Taejin Lee
We evaluate four-gauge-particle tree level scattering amplitudes using the Polyakov string path integral in the proper-time gauge, where the string path integral can be cast into t…
Four-Graviton Scattering and String Path Integral in the Proper-time gauge
Taejin Lee
We evaluate the four-closed-string scattering amplitude, using the Polyakov string path integral in the proper-time gauge. By identifying the Fock space representation of the four-…
