High Energy Scattering Amplitudes of Superstring Theory
Chuan-Tsung Chan, Jen-Chi Lee, Yi Yang
We use three different methods to calculate the proportionality constants among high-energy scattering amplitudes of different string states with polarizations on the scattering pl…
Generalizations of Lunin-Maldacena transformation on the background
R. C. Rashkov, K. S. Viswanathan, Yi Yang
In this paper we consider a simple generalization of the method of Lunin and Maldacena for generating new string backgrounds based on TsT-transformations. We study multi-shift $Ts.…
Comments on the high energy limit of bosonic open string theory
Chuan-Tsung Chan, Pei-Ming Ho, Jen-Chi Lee +2
In previous works, ratios among four-point scattering amplitudes at the leading order in the high-energy limit were derived for the bosonic open string theory. The derivation was b…
High-energy zero-norm states and symmetries of string theory
Chuan-Tsung Chan, Pei-Ming Ho, Jen-Chi Lee +2
High-energy limit of zero-norm states (HZNS) in the old covariant first quantized (OCFQ) spectrum of the 26D open bosonic string, together with the assumption of a smooth behavior…
Solving all 4-point correlation functions for bosonic open string theory in the high energy limit
Chuan-Tsung Chan, Pei-Ming Ho, Jen-Chi Lee +2
We study the implication of decoupling zero-norm states in the high-energy limit, for the 26 dimensional bosonic open string theory. Infinitely many linear relations among 4-point…
Anatomy of Zero-norm States in String Theory
Chuan-Tsung Chan, Jen-Chi Lee, Yi Yang
We calculate and identify the counterparts of zero-norm states in the old covariant first quantised (OCFQ) spectrum of open bosonic string in two other quantization schemes of stri…
