Dr. Daniel Pitonyak, assistant professor of physics, co-authored “First Global QCD Analysis of the TMD g1T from Semi-Inclusive DIS Data,” which was published by the peer-reviewed journal Physical Review D. This work provides insight into how longitudinally polarized quarks move inside a transversely polarized proton. It is the second piece Dr. Pitonyak has had published by Physical Review D in less than a year, and both research projects were supported by his grant from the National Science Foundation.

Dr. Daniel Pitonyak, assistant professor of physics, recently gave three invited or contributed talks, and two physics majors—Michel Malda ’22 and Ben Gordon ’22—gave talks at major conferences. On Oct. 13, Malda presented “Updated QCD Global Analysis of Single Transverse-Spin Asymmetries” and Gordon spoke about “Analysis of the cos(2φ) Modulation in Semi-Inclusive Deep-Inelastic Scattering” at the American Physical Society Division of Nuclear Physics Fall Meeting, where Dr. Pitonyak gave a contributed talk, “Update on the Jefferson Lab Angular Momentum Collaboration’s Global Analysis of SSAs.”
Dr. Pitonyak also gave an invited talk, “Status of Phenomenology for the Transversity Distribution,” at the 5th Workshop on the QCD Structure of the Nucleon on Oct. 4, followed by “Small-x Helicity Evolution and the Proton Spin Puzzle” at the 24th International Spin Symposium on Oct. 22.
