Selection rules for the S-Matrix bootstrap
Anjishnu Bose, Aninda Sinha, Shaswat S Tiwari
We examine the space of allowed S-matrices on the Adler zeros' plane using the recently resurrected (numerical) S-matrix bootstrap program for pion scattering. Two physical quantit…

Relative entropy in scattering and the S-matrix bootstrap
Anjishnu Bose, Parthiv Haldar, Aninda Sinha +2
We consider entanglement measures in 2-2 scattering in quantum field theories, focusing on relative entropy which distinguishes two different density matrices. Relative entropy is…
