[Theory-seminars] Theory Seminar Monday - Ian Low

[Colin Egerer]

Hello All,

This coming Monday, February 13th, at 1:00 PM (EST), Ian Low will give our first hybrid theory seminar of the New Year. If you will be on-site and are comfortable doing so, please join us in room L102 of CEBAF Center. Otherwise, Ian's seminar will also be provided virtually on our usual ZoomGov link: https://jlab-org.zoomgov.com/j/1611179843?pwd=M09CNTFpbFVZSW1IQlhIMGp3RUVHUT09

Please see below for the title and abstract.

Theory Seminar
Monday, February 13th at 1:00 PM

Ian Low (Northwestern University)
will discuss "Entanglement Suppression and Emergent Symmetries in Low-energy QCD"

Abstract:
We study low-energy scatterings of spin-1/2 baryons from the perspective of quantum information science, focusing on the correlation between entanglement minimization and the appearance of accidental symmetries. Interactions of the octet baryons below the pion threshold are described by contact operators in an EFT of QCD. Despite there being 64 channels in the 2-to-2 scattering, only 6 independent operators in the EFT are predicted by SU(3) flavor symmetry. We show that successive entanglement minimization in SU(3)-symmetric channels lead to increasingly large emerging symmetries in the EFT. In particular, we identify scattering channels whose entanglement suppression would lead to emergent SU(6), SO(8) and SU(8) flavor symmetries, as well as SU(16) spin-flavor symmetry.

Have a pleasant weekend!
Caroline, Colin & Patrick
