2WFA.00001: Structure of the pion and kaon in lattice QCD Invited Speaker: Huey-Wen Lin I present the first direct lattice-QCD calculations of the Bjorken-x dependence of the pion and kaon structure within the framework of large-momentum effective theory (LaMET), sometimes called the "quasi-PDF method". The ongoing studies are investigating the quark parton distribution functions (PDFs), distribution amplitudes (DAs) and generalized parton distribution (GPDs). |

2WFA.00002: First Simultaneous Extraction of Parton Distributions and Fragmentation Functions from a Global QCD Analysis Invited Speaker: Nobuo Sato We perform the first global QCD analysis of inclusive and semi-inclusive deep-inelastic scattering and single-inclusive e+e- annihilation data, simultaneously fitting the parton distribution and fragmentation functions using the Monte Carlo nested sampling method. Without imposing SU(3) symmetry relations, we find the strange polarization to be very small, consistent with zero for both inclusive and semi-inclusive data, which provides a resolution to the strange quark polarization puzzle. We further quantify the impact of semi-inclusive deep-inelastic scattering data on the determination of the unpolarized strange and antistrange distributions. |

2WFA.00003: Measurements of parton structure of nucleons and nuclei via Drell-Yan process at Fermilab Invited Speaker: Kenichi Nakano SeaQuest at FNAL is a fixed-target experiment to measure the Drell-Yan process in p+p and p+A, using the 120-GeV proton beam and targets of liquid hydrogen, liquid deuterium, carbon, iron and tungsten. During the course of operations, completed in July 2017, it recorded data from 1.4*10^18 protons on the various targets.
