Linear Relations of High Energy Absorption/Emission Amplitudes of D-brane
Jen-Chi Lee, Yi Yang
We calculate the absorption amplitudes of a closed string state at arbitrary mass level leading to two open string states on the D-brane at high energies. As in the case of Domain-…
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…
Notes on High Energy Limit of Bosonic Closed String Scattering Amplitudes
Chuan-Tsung Chan, Jen-Chi Lee, Yi Yang
We study bosonic closed string scattering amplitudes in the high-energy limit. We find that the methods of decoupling of high-energy zero-norm states and the high-energy Virasoro c…
