"Finding out what you're made of: Partons on the lattice"

Joe Karpie , Columbia University
[Host: Ishara Fernando]

Understanding the structure of hadrons from first principles has been a long standing issue. Within the last decade, lattice QCD calculations have begun to probe the partonic structure of pions and nucleons. The "pseudo-PDF" approach has been successful in calculating the parton distribution functions of nucleons and pions and calculations with control of the systematic errors are underway. To relate the PDF and lattice calcuable matrix elements, integral equations must be inverted using similar techniques to those employed by phenomenological analyses of 1 and 3 dimensional parton distributions. Moreover experimental and lattice results can be combined within this inverse problem to obtain better results than they could individually.
