Residues of bosonic string scattering amplitudes and the Lauricella functions
Sheng-Hong Lai, Jen-Chi Lee, Yi Yang
We calculate explicitly residues of all n-point Koba-Nielsen (KN) amplitudes by using on-shell recursion relation of string scattering amplitudes (SSA). In addition, we show that t…

The exact SL(K+3,C) symmetry of string theory
Sheng-Hong Lai, Jen-Chi Lee, Yi Yang
By using on-shell recursion relation of string scattering amplitudes (SSA), we show that all n-point SSA of the open bosonic string theory can be expressed in terms of the Lauricel…

Comment on "High Energy Symmetry of String Theory"
Sheng-Hong Lai, Jen-Chi Lee, Yi Yang
Following the recent discovery of the Lauricella string scattering amplitudes (LSSA) and their associated exact SL(K+3,C) symmetry, we give a brief comment on Gross conjecture rega…
