36. Excited states and scattering phase shifts from lattice QCD

Prof. Colin Morningstar (Carnegie Mellon University)

4/9/15, 11:30 AM

invited talk

Progress in computing excited state energies and meson-meson scattering phase shifts in lattice QCD are described. Such calculations are now possible using a stochastic method of treating the low-lying modes of quark propagation that exploits Laplacian Heaviside quark-field smearing. Level identification with a variety of probe interpolating operators is discussed.

12. Physics Program for Studying GPDs at Jefferson Lab

Dr Stepan Stepanyan (Jefferson Lab)

invited talk

A broad program for studying the quark and gluon structure of hadrons is underway at Jefferson Lab. The cornerstone of this program is understanding the nucleon structure in the framework of Generalized Parton Distributions (GPDs). The GPDs take the description of the internal structure of the nucleon to a new level by providing access to, among other things, the correlations between the...
