Qipeng Hu (胡启鹏) is currently a postdoc at Lawrence Livermore National Laboratory. He received his PhD from the University of Science and Technology of China in 2017. Following that, he joined the University of Colorado Boulder as a postdoc from 2017 to 2020. Based on data collected by the ATLAS experiment, his primary research focus is on measuring modifications of hard processes in heavy-ion collisions such as heavy flavor production, quarkonium production and jet substructure. He also plays leading role in the study of collectivity phenomena of soft particles in small collision systems. From 2019 to 2021 he led the electroweak and quarkonium physics in the ATLAS heavy ion working group. He is now responsible for ATLAS trigger menu and reconstruction software developments for the scheduled 2022 heavy ion runs.
Relativistic heavy-ion collisions create a strongly interacting QCD medium, called quark-gluon plasma (QGP), which expanses like a nearly perfect fluid. Partons from hard scattering lose energy through interactions with the color-charged QGP medium. The medium induced energy loss is one of the major signatures of the QGP. The seminar presents recent ATLAS measurements on differential energy losses of jet and heavy flavor hadrons based on LHC Run-2 data. By comparing the results with model calculations, the implications for our understanding of the QGP properties will be explored.
