In this proceedings, an overview of selected experimental results in heavy-ion collisions focusing on measurements at high energy frontier that explores the high temperature and low baryochemical potential part of the QCD phase diagram is presented. Due to the space limitations only a few prominent results can be highlighted here with a primary focus on hard probes studies with heavy-flavor particles, jets, and quarkonia measured by the experiments at the LHC CERN and RHIC at BNL. The interested reader is therefore kindly referred to the individual contributions at the conference.
