NPA Seminar, Isaac Mooney, Wayne State University, “Jet substructure measurements in proton-proton and proton-gold collisions at RHIC”

Measurements of the substructure of high-momentum jets produced in proton-proton (pp) collisions give insight into fundamental aspects of QCD, from the production of highly virtual partons, to their subsequent radiation and hadronization. Additionally, once the evolution of jets in vacuum is calibrated, it is possible to study potential modification to jet substructure due to interaction with the cold nuclear medium present in proton-gold (pAu) collisions. I will present substructure measurements by the STAR Collaboration (the first fully corrected inclusive jet mass in pp collisions at RHIC: Physical Review D 104, 052007 (2021); the first fully corrected jet substructure in pAu collisions at RHIC: in preparation). Additionally, I will compare experimental results to theoretical calculations and models, and discuss the implications of these results.
There will be a luncheon with the speaker from 12-1 p.m. in WL-216. Lunch will be provided for people on a first-come, first-served basis for people who RSVP by Wednesday, July 21st: https://tinyurl.com/npa-signup
