Neutral-Fermion constructions of factorial $g p$ -and $g q$ -Functions

Koushik Brahma, Takeshi Ikeda, Shinsuke Iwao +1

We develop neutral-fermionic constructions for the factorial $g p$ -and $g q$ -functions introduced by Nakagawa and Naruse, which are respectively dual to the factorial $GQ$ - and $GP$ -…

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 $n$ -point $H S S A$ of open bosonic string theory. This stringy scaling loop expansion contains finite number of vacu…

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…
