Add to Calendar 2/23/2018 12:00 pm 2/23/2018 America/Chicago High Energy/Medium Energy Physics Seminar: "Frontiers in Lattice Nucleon Structure." DESCRIPTION:

Recently, there have been rapid developments in lattice-QCD calculations of nucleon structure. We are now entering a precision era for nucleon matrix elements, where calculations are done at the physical pion mass with fully controlled systematics. This was first achieved by the Precision Neutron-Decay Matrix Element (PNDME) collaboration. I will discuss a couple examples of how our high-quality precision  nucleon inputs can be applied to searches for new physics.

In addition, we overcame a longstanding obstacle, and for the first time in lattice-QCD are able to directly calculate the Bjorken-x dependence of the quark, helicity and transversity distributions. Ongoing exploratory studies of the quark and antiquark flavor asymmetry of these distributions will be discussed. This breakthrough opens an exciting new frontier calculating more complicated quantities, such as gluon structure, transverse-momentum dependent structure and more, which will complement existing theoretical programs for the upcoming Electron-Ion Collider (EIC).
