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.
