- ItemDIRECTED FLOW MEASUREMENTS USING THE SPECTATOR PLANE WITH THE CMS DETECTOR IN THE 2018 PB-PB RUN AT √SNN = 5.02 TEV(2022) Adams, Eric Brian; Mignerey, Alice C; Chemistry; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)The Compact Muon Solenoid (CMS) is used along with the Spectator Reaction PlaneDetectors (SRPD) to measure the directed flow signal, using spectator neutrons, in the 2018 √sNN = 5.02 TeV Pb-Pb run with the Large Hadron Collider (LHC) at CERN. The Hadron Forward detector (HF), along with the tracker, is also used to measure the directed flow signal but instead uses participant nucleons. The results from the CMS 2018 Pb-Pb spectator and participant measurements of the directed flow signal are compared. These are the first spectator plane directed flow measurements from the CMS detector. The results are compared to the Pb-Pb collisions as reported by the A Large Ion Collider Experiment (ALICE) collaboration in 2013 .
