Infrared Consistency and the Uniqueness of String Amplitudes
Yu-tin Huang, Shi-Lin Wan, Zhuo-Hui Wang +1
Recent work has shown that maximal supersymmetry, combined with a particular scalar-parity condition at six points, imposes nonlinear constraints on four-point effective field theo…

Analytic Bootstrap of the Veneziano Amplitude
Shi-Lin Wan, Shuang-Yong Zhou
We analytically prove that the Veneziano amplitude is the unique outcome of a dual bootstrap based on dispersive sum rules, unitarity, and a small amount of additional stringy inpu…

Matrix moment approach to positivity bounds and UV reconstruction from IR
Shi-Lin Wan, Shuang-Yong Zhou
Positivity bounds in effective field theories (EFTs) can be extracted through the moment problem approach, utilizing well-established results from the mathematical literature. We g…
