Dr. Pavel Nadolsky earned a Ph.D. degree (2001) in Physics at Michigan State University. He worked as a post-doc at Southern Methodist University (SMU) in 2001 - 2004 and Argonne National Laboratory in 2004-2007. In 2008, he began his appointment as an assistant professor at SMU, where he is currently doing research on theory of elementary particles at hadron colliders, which explores physical objects at tiniest distances accessible to modern science. His research focuses on basic forces existing in nature and microscopic events that drive the evolution of the Universe.

Abstract

An overwhelming number of theoretical predictions for hadron colliders  requires parton distribution functions (PDFs) in the proton. Understanding  of PDFs beyond the current level is critical for studies of the Higgs  mechanism and new physics searches in the high-luminosity runs of the  Large Hadron Collider. The ongoing revolution in computations of  perturbative QCD demands comparably accurate nonperturbative PDFs.  Determination of PDFs from the data combines continued advancements in quantum field theory, experimental measurements, and  data science/machine learning. On the example of recent PDFs by the  CTEQ-TEA (CT) and PDF4LHC groups, I review the progress in determination  of PDFs and physics issues arising in their numerous applications.
