Positivity of the hypergeometric Coon amplitude

Journal of High Energy Physics
We utilize a novel method for the partial-wave unitarity recently suggested in [1] to analyse the hypergeometric Coon amplitude. In this approach we use a new type of harmonic numbers as a basis.

Non-relativistic heterotic string theory

Journal of High Energy Physics
In this work we consider heterotic-gravity as the low-energy approximation to heterotic string theory. We define a consistent non-relativistic limit of heterotic gravity that includes the Yang-Mills Chern-Simons term.

Instantons in sine-Liouville theory

Journal of High Energy Physics
We compute instanton corrections to the partition function of sine-Liouville (SL) theory, which provides a worldsheet description of two-dimensional string theory in a non-trivial tachyon background.

Stringy scaling of multi-tensor hard string scattering amplitudes and the K-identities

Journal of High Energy Physics
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.

Cuts and contours

Journal of High Energy Physics
The traditional formulation of string amplitudes via worldsheet integrals provides a parametrization of the moduli space that fails to expose the complete singularity structure of the amplitudes.

Relations between closed string amplitudes and mixed string amplitudes at tree-level

Journal of High Energy Physics
This paper investigates the relationships between closed and mixed string amplitudes at the tree level in string theory. Through the analytic continuation of complex variables, we establish a factorization of closed string amplitudes into those involving
