Computing nucleon EDM on a lattice
Abstract
I will discuss briefly recent changes in the methodology of computing the baryon EDM on a lattice. The associated correction substantially reduces presently existing lattice values for the proton and neutron thetainduced EDMs, so that even the most precise previous lattice results become consistent with zero. On one hand, this change removes previous disagreements between these lattice results and the phenomenological estimates of the nucleon EDM. On the other hand, the nucleon EDM becomes much harder to compute on a lattice. In addition, I will review the progress in computing quark chromoEDMinduced nucleon EDM using chiral quark action.

This book presents information on the following topics: QCD at finite temperature and baryon number density; critical behavior in onic matter; Monte Carlo renormalization group; the lookahead fermion algorithm; the potential between static quarks in SU (2) lattice gauge theory with dynamical fermions; the texpansion and lattice of QCD; lattice Higgs models; relaxation and correlations in time in a finite volume; topology in lattice gauge theory; hadron mass calculation on a 24/sup 3/ x 48 lattice; calculation of weak matrix elements; the chiral limit in lattice QCD; potentials; quenched hadron masses using a 16/sup 4/ lattice; a new method formore » 
Lattice QCD Application Development within the US DOE Exascale Computing Project
In October, 2016, the US Department of Energy launched the Exascale Computing Project, which aims to deploy exascale computing resources for science and engineering in the early 2020's. The project brings together application teams, software developers, and hardware vendors in order to realize this goal. Lattice QCD is one of the applications. Members of the US lattice gauge theory community with significant collaborators abroad are developing algorithms and software for exascale lattice QCD calculations. We give a short description of the project, our activities, and our plans. 

Insight into nucleon structure from lattice calculations of moments of parton and generalized parton distributions
This talk presents recent calculations in full QCD of the lowest three moments of generalized parton distributions and the insight they provide into the behavior of nucleon electromagnetic form factors, the origin of the nucleon spin, and the transverse structure of the nucleon. In addition, new exploratory calculations in the chiral regime of full QCD are discussed.
