Quark Matter - International Conference on Ultra-relativistic Nucleus-Nucleus Collisions is the largest conference on the topic of heavy-ion collisions and the quark-gluon plasma, medium created in such collisions. In 2019, it took place in Wuhan, China. STAR teams from FNSPE and NPI CAS were represented by 4 students and postdocs. Barbara Trzeciak was invited to give a talk titled Quenching of heavy and light flavor jets: experimental overview. Leszek Kosarzewski, Lukas Kramarik and Jan Vanek presented posters with the recent results from the STAR experiment at BNL.
Dzmitry Makatun successfully defended PhD in mathematical engineering at the Faculty of Nuclear Sciences and Physical Engineering of Czech Technical University on September 17th 2018. He previously obtained a Master degree in Physics at the Department of Physics of Belarusian State University. His PhD thesis proposes a novel scheduling approach for large-scale data-intensive distributed computations with application in High Energy and Nuclear Physics (HENP). A large part of the work is dedicated to detailed simulations of distributed data production in HENP which are based on data from real systems. Supervisors of Dzmitry’s research were Jerome Lauret (STAR, Brookhaven National Laboratory), Hana Rudova (Faculty of Informatics, Masaryk University) and Michal Sumbera (Nuclear Physics Institute of Czech Academy of Science). The opponents of the thesis defence were Philippe Charpentier (LHCb, CERN) and Roman Bartak (Faculty of Mathematics and Physics, Charles University). This PhD study became a positive example of scientific collaboration across distinct countries, institutions, and domains. After the graduation, Dzmitry continues his path in big data and proceeds his career in a multinational banking company present in Prague.
More than 65 scientists attended the prestigious international Hot Quarks 2018 conference (7-14 September). This workshop on heavy-ions, aimed particularly at young scientists and students, took place on the picturesque Texel Island in the Netherlands and was co-organised by Dr. Jana Bielčíková, the leader of the STAR group at the Nuclear Physics Institute of Czech Academy of Sciences. Two students of the Czech Technical University in Prague, Ing. Jan Vaněk and Ing. Oliver Matonoha, had the privilege to come to this conference and present their latest results from the research they conduct at the STAR experiment. Jan talked about his analysis of the open-charmed mesons and what can we learn from it about the quark energy losses in the Quark Gluon Plasma, whereas Oliver presented measurements on the Upsilon production and the methods to use them to study the plasma temperature.
RNDr. Petr Chaloupka, Ph.D. (FNSPE CTU in Prague) has become a one out of three co-Conveners for Heavy Flavor Group on the experiment STAR.
Petr graduated from Charles University in 2001 and continued his Ph.D. studies. During this time he worked at the NPI CAS and was on long stays in BNL or Berkeley. From 2012 he works at the FNSPE, where beside the experimental studies of ultra-relativistic heavy-ion collisions at STAR experiment at BNL also teaches Subnuclear Physics, Introduction to experimental physics 1, 2 and supervising Bc., MSc. and Ph.D. students.
Na festivale Colours of Ostrava (18.-21.7.2018) se tým studentek a studentů z KF a KDAIZ zúčastnil s fyzikální show, která probíhala každý den na společném stánku se Světem techniky Ostrava. Účastníci se mohli podívat a vyzkoušet experimenty z jaderné a částicové fyziky. Studenti také přispěli do programu přednášek o fyzice Science Garden (https://www.colours.cz/ucinkujici/science-garden), která je součástí oficiálního programu Meltingpot Plus. Tento nápad vznikl v rámci skupiny IPPOG CR, která se zaobírá popularizací částicové fyziky a naše účast je podpořená projektem BNL-CZ.
Scientists from FNSPE CTU in Prague and NPI CAS with colleagues from the other countries participating in the STAR experiment revealed that the fluid produced in heavy ion collisions (quark-gluon plasma) is the most vortical system so far observed. The discovery was published in the prestige magazine Nature and placed it on the title page.
