Scattering Equations as the lowest order K-identities in the calculation of Stringy Scaling of Hard String Scattering Amplitudes
Sheng-Hong Lai, Jen-Chi Lee, Yi Yang
We prove explicitly the n-point K-identities we proposed previously in the calculation of one tensor hard string scattering amplitudes (HSSA). These K-identities were the key to ob…
Stringy scaling of multi-tensor hard string scattering amplitudes and the K-identities
Sheng-Hong Lai, Jen-Chi Lee, Yi Yang
We calculate n-point hard string scattering amplitudes (HSSA) with n-2 tachyons and 2 tensor states at arbitrary mass levels. We discover the stringy scaling behavior of these HSSA…
Stringy Scaling
Sheng-Hong Lai, Jen-Chi Lee, Yi Yang
We discover a general stringy scaling behavior for 1. All n-point hard string scattering amplitudes (HSSA) and 2. A class of n-point Regge string scattering amplitudes (RSSA) to al…
The stringy scaling loop expansion and stringy scaling violation
Sheng-Hong Lai, Jen-Chi Lee, Yi Yang
We propose a systematic approximation scheme to calculate general -point of open bosonic string theory. This stringy scaling loop expansion contains finite number of vacu…
