Maximum Entanglement in Particle Physics
Author: Alba Cervera
We present an analysis of entanglement generation by fundamental interactions. We analyze the final state amplitudes in terms of helicities and polarizations of the incoming and outgoing particles to see for which energies and configurations entanglement is allowed. As maximum entanglement is generated in all processes studied, we propose to use this property to find constraints in interaction structures and Standard Model free parameters. As an example of the first application, we study a QED model without imposing gauge symmetry and find standard QED as a unique solution that allows maximum entanglement generation. We go forward and study which constraints this idea could impose on weak interactions to find an estimation of weak mixing angle.
