Five-point partial waves, splitting constraints and hidden zeros
Arnab Priya Saha, Aninda Sinha
We introduce a partial-wave basis for the double residues of five-point tree amplitudes involving identical external scalar particles, decomposing them into exchanges of definite s…

A stringy dispersion relation for field theory
Faizan Bhat, Arnab Priya Saha, Aninda Sinha
We derive a local, crossing symmetric dispersion relation (CSDR) for 2-2 scattering amplitudes with a parametric ambiguity motivated by string theory. Various limits of the paramet…

Bootstrapping string models with entanglement minimization and Machine-Learning
Faizan Bhat, Debapriyo Chowdhury, Arnab Priya Saha +1
We present a new approach to bootstrapping string-like theories by exploiting a local crossing symmetric dispersion relation and field redefinition ambiguities. This approach enabl…
