Patterns of High energy Massive String Scatterings in the Regge regime
Sheng-Lan Ko, Jen-Chi Lee, Yi Yang
We calculate high energy massive string scattering amplitudes of open bosonic string in the Regge regime (RR). We found that the number of high energy amplitudes for each fixed mas…
Kummer function and High energy String Scatterings
Sheng-Lan Ko, Jen-Chi Lee, Yi Yang
Based on a summation algorithm for Stirling number identity developed recently, we discover that the ratios calculated previously among high energy string scattering amplitudes in…
Scatterings of Massive String States from D-brane and Their Linear Relations at High Energies
Chuan-Tsung Chan, Jen-Chi Lee, Yi Yang
We study scatterings of bosonic massive closed string states at arbitrary mass levels from D-brane. We discover that all the scattering amplitudes can be expressed in terms of the…
Zero-Norm States and Superstringy Symmetries
Jen-Chi Lee
We identify spacetime symmetry charges of the bosonic sector of 10D superstring theory from an infinite number of zero-norm states (ZNS) in the old covariant first quantized string…
Power-law Behavior of Strings Scattered from Domain-wall at High Energies and Breakdown of their Linear Relations
Chuan Tsung Chan, Jen-Chi Lee, Yi Yang
In contrast to the common wisdom, we discover that, instead of the exponential fall-off of the form factors with Regge-pole structure, the high-energy scattering amplitudes of stri…
