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…
Cubic Closed String Field Theory on a Double Layer
Taejin Lee
Various studies have attempted to extend the Witten's cubic open string field theory to the cubic closed string field theory, which may describe Einstein gravity in the low energy…
Graviton and Massive Symmetric Rank-Two Tensor in String Theory
Taejin Lee, Hayun Park
Spin-two particles appear in the spectra of both open and closed string theories. We studied a graviton and massive symmetric rank-two tensor in string theory, both of which carry…
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…
