Dr. Daniel Pitonyak, assistant professor of physics, gave a talk, “Multi-Parton Correlations in SIDIS, electron-positron, and proton-proton collisions,” at the QCD Evolution 2019 Conference at Argonne National Lab in May. The conference supports and guides the high-energy nuclear physics programs at facilities such as Jefferson Lab, the Relativistic Heavy Ion Collider at Brookhaven National Lab, Fermi National Accelerator Lab, and Large Hadron Collider at CERN. The workshop is also central to the planning for the next-generation nuclear physics facility in the United States, the Electron Ion Collider.

Dr. Daniel Pitonyak, assistant professor of physics, was invited to give a talk at the Workshop on Novel Probes of Nucleon Structure in SIDIS, e+e- and pp (FF2019) at Duke University in March. The workshop will bring together theorists and experimentalists to discuss new results with the goal of improving our understanding of the internal structure and formation of nuclear matter. Dr. Pitonyak’s presentation is “Higher-Twist Fragmentation Functions in Transverse-Spin Observables.”

Dr. Daniel Pitonyak, assistant professor of physics, co-authored an article with colleagues from Penn State, UCLA, New Mexico State, and Los Alamos National Lab that was published Jan. 14 in the Journal of High Energy Physics. The article, “Polarized hyperon production in single-inclusive electron-positron annihilation at next-to-leading order,” focused on their research on how particles called hyperons are formed from the energy released when an electron and positron travel close to the speed of light, collide, and then annihilate each other.
