Description

Quantum information science offers a fresh perspective to think about quantum field theory. In this talk, I look at the connection between entanglement and symmetries in low-energy scattering of spin-$\frac{1}{2}$ baryons. The baryons transform as an octet under the $SU(3)$ flavor symmetry and their interactions below the pion threshold are described by contact operators in an effective field theory (EFT) of QCD. I will show that successive entanglement minimization in $SU(3)$-symmetric scattering channels are correlated with increasingly large emergent symmetries in the EFT.
