The XXVIIIth International Conference on Ultra-relativistic Nucleus-Nucleus Collisions – was held in Wuhan, China, during November 4-9, 2019. The MIT Heavy Ion Group sent a 10-member delegation to the conference and presented 2 plenary talk, 4 parallel talks, and 2 posters. Early in the morning of October 31, all students and postdocs attened the student lecture at the Science Hall of Central China Normal University.
On Nov 4, our students Ran, Michael, and Molly presented their posters during the poster section. On Nov 6, our group gave 4 parallel talks. In the morning, Molly presented the new CMS results on Jet nuclear modification factor using the 2015 CMS PbPb datasets entitled “Mapping the redistribution of jet energy in PbPb collisions using jets with various radius parameters with CMS“. Then, in the early afternoon, Ran gave a parallel talk on “Study of in-medium momentum broadening with photon-jet momentum correlations in PbPb collisions at 5.02 TeV in the CMS experiment“, showing the photon-jet correlations resulstion with the CMS 2015 PbPb datasets. Next, Zhaozhong presented the Non-Prompt J/ψ, B meson, and the new Ds studies entitled “Studies of Strange and Non-Strange Beauty Productions in PbPb Collisions with the CMS Detector “. Followed by Zhaozhong’s presentation, Yen-Jie reported the first exciting observation of exotic hadron X(3872) in PbPb collision with CMS experiment. His talk “Evidence of X(3872) and studies of its prompt production in PbPb collisions“. has received a lot of attention and lead to discussions from the heavy-ion physics community.
In the morning of On Nov 8, our group postdocs gave two plenary talks. The first talk was given by Yi on the experimental overview of jet substructure entitled “Jet substructure and parton splitting: an experimental overview“.
After that, Jing presented the experimental overview of open heavy flavor physics: “Heavy Quark production and energy loss: Experiments“. Both of the talks were excellent and led to extensive discussions among the audience.
Everyone in our group worked hard on their analysis to prepare for Quark Matter 2019. Some measurements using CMS 2018 PbPb new data have been presents. We will present more important and exciting results with the 2018 CMS PbPb dataset in Hard Probes 2020!
