Entanglement produced in pi-pi and pi-N scattering

Recently, minimization of spin entanglement in baryon-baryon scattering has been shown to explain a SU(16) symmetry revealed by lattice QCD. Here we test the extent to which isospin entanglement is minimized in pi-pi and pi-N scattering. This is done by computing the entanglement power, a measure of entanglement due to interaction, of the pi-pi and pi-N S-matrices. Lastly, consequences of entanglement minimization for scattering with pions as well as comparisons to large N_c QCD will be discussed.
