Scientists working in the large infrastructure BNL-CZ, in co-operation with other Czech institutions co-organized the largest conference in particle physics ICHEP2020 taking place from July 28 to August 6, 2020 in online mode due to the covid-19 pandemic. The conference was launched with a parallel program in 17 specialized sections. A total of 3,000 scientists from all over the world took part in it, making it the largest in the history of particle physics. Particle physics is one of the most important research topics at CTU where our involvement in research at the Brookhaven National Laboratory is crucial. Many of our colleagues are involved in the organization of the conference itself, e.g. Jana Bielčíková co-coordinated the program committee of the conference, Jaroslav Bielčík co-coordinated the preparation of the program for the public, Barbara Trzeciak co-heads the Heavy Ion Physics section, Miroslav Myška co-heads the Education and Popularization section. In addition, many of our students participate in the technical implementation of the conference. A number of colleagues from BNL-CZ from the STAR experiment presented directly at the conference with expert talks:
- Leszek Kosarzewski about Upsilon meson production at the STAR experiment
- Lukáš Kramárik about production of charmed quarks at the STAR experiment
- Jakub Česka about Monte Carlo simulations of Upsilon meson production
- Tomáš Truhlář abpout production of pion-pion, kaon-kaon a proton-antiproton pairs
- Jan Vaněk about D+- meson production at the STAR experiment
- Jakub Cimerman abourt correlation femtoscopy in heavy-ion collisions
At the beginning of December 2019, beam started to circulate in the RHIC and first collisions were recorded at the STAR detector. Our PhD students Jan Vanek and Lukas Kramarik, who work as expert on the ZDC subdetector, where at place to ensure its functionality during the long 6 month of data-taking. The anniversary 20th physics run will focus on low-energy collisions, that could help to find the critical point of the QCD phase diagram. More information is at this link.
The European Physical Society Conference on High Energy Physics (EPS-HEP) is one of the major international conferences that reviews the field every second year since 1971 and is organized by the High Energy and Particle Physics Divison of the European Physical Society. In 2019 the EPS-HEP conference took place in Ghent, Belgium from 10 to 17 July. Dr. Leszek Kosarzewski had his presentation on Quarkonium production measured by the STAR experiment and Ing. Robert Licenik (NPI CAS) presented Measurement of open-charmed hadron production in Au+Au collisions at √sNN = 200 GeV with the STAR experiment.
Many students and researchers from FNSPE CTU and NPI CAS attended STAR collaboration analysis meeting at the AGH University of Science and Technology, Cracow, Poland, on 19-23 August 2019. They presented their recent scientific results supported by the use of infrastructure BNL-CZ.

Our colleagues helped to organize the 11th International Workshop on Multiple Partonic Interaction at the LHC which was hosted by the Department of Physics, Faculty of Nuclear Sciences and Physical Engineering, FNSPE CTU in Prague, Czech Republic, on 18-22.11.2019. This workshop brings together the world's leading experts from theory and LHC experiments to discuss the latest progress on the physics relevant to the Multiple Partonic Interactions. Dr. Jana Bielčíkova had her presentation titled Overview of hard and soft probe measurements with STAR at RHIC and Dr Leszek Kosarzewski had a presentation on the Charged particle multiplicity dependence of quarkonium production measured by the STAR experiment.
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.
