S-brane Actions
Koji Hashimoto, Pei-Ming Ho, John E. Wang
We derive effective actions for Spacelike branes (S-branes) and find a solution describing the formation of fundamental strings in the rolling tachyon background. The S-brane actio…
Virasoro Algebra for Particles with Higher Derivative Interactions
Pei-Ming Ho
In this paper we show that the worldline reparametrization for particles with higher derivative interactions appears as a higher dimensional symmetry, which is generated by the tru…
Perturbative Approach to Higher Derivative Theories with Fermions
Tai-Chung Cheng, Pei-Ming Ho, Mao-Chuang Yeh
We extend the perturbative approach developed in an earlier work to deal with Lagrangians which have arbitrary higher order time derivative terms for both bosons and fermions. This…
Cubic String Field Theory in pp-wave Background and Background Independent Moyal Structure
Chong-Sun Chu, Pei-Ming Ho, Feng-Li Lin
We study Witten open string field theory in the pp-wave background in the tensionless limit, and construct the N-string vertex in the basis which diagonalizes the string perturbati…
Noncommutative Spacetime, Stringy Spacetime Uncertainty Principle, and Density Fluctuations
Robert Brandenberger, Pei-Ming Ho
We propose a variation of spacetime noncommutative field theory to realize the stringy spacetime uncertainty relation without breaking any of the global symmetries of the homogeneo…
Noncommutative D-brane and Open String in pp-wave Background with B-field
Chong-Sun Chu, Pei-Ming Ho
The open string ending on a D-brane with a constant B-field in a pp-wave Ramond-Ramond background is exactly solvable. The theory is controlled by three dimensionful parameters: al…
