  1. 62. Recent results on quasi parton distributions
    Jianhui Zhang (University of Regensburg)
    2/2/17, 11:00 AM
    In recent years impressive progress has been made on directly calculating the full x-dependence of parton quantities from the quasi ones that are defined as spatial correlators. In this talk, I will discuss the quasi parton distribution and some recent results on its application to calculating parton distributions.

  2. 44. Renormalization Issues on Long-Link Operators
    Prof. Martha Constantinou (Temple University)
    2/2/17, 11:25 AM
    Parton distribution functions (PDFs) provide important information on the quark and gluon structure of hadrons which, at leading twist, they give the probability of finding a specific parton in the hadron carrying certain momentum and spin, in the infinite momentum frame. Due to the fact that PDFs are light-cone correlation functions, they cannot be computed directly on a Euclidean...

  3. 98. Gradient flow renormalization of Quasi parton distributions
    Prof. Kostas Orginos (William and Mary / JLab)
    2/2/17, 11:50 AM
    Gradient flow, is a method that allows us to construct lattice quasi PDFs that are finite in the continuum limit. In the small flow time limit, the moments of the smeared quasi PDFs are proportional to those of the light-front PDFs. These proportionality coefficient obey a renormalization group equation that allows us to derive renormalization scale evolution equations for the matching kernel...

  4. 28. Quark orbital dynamics in the nucleon from Lattice QCD -- from Ji to Jaffe-Manohar orbital angular momentum
    Michael Engelhardt (New Mexico State University)
    2/2/17, 12:15 PM
    Quark orbital angular momentum (OAM) in the nucleon can be evaluated directly by employing a Wigner function embodying the simultaneous distribution of parton transverse position and momentum. This distribution can be accessed via a generalization of the nucleon matrix elements of quark bilocal operators used to define transverse momentum dependent parton distributions (TMDs). By supplementing...
