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…

Proof of the Classical Soft Graviton Theorem in D=4
Arnab Priya Saha, Biswajit Sahoo, Ashoke Sen
Classical subleading soft graviton theorem in four space-time dimensions determines the gravitational wave-form at late and early retarded time, generated during a scattering or ex…
