"Quark Matter highlights"

Alexander Milov
WIS

Abstract: We will show and discuss selected highlights from the new experimental results presented at the XXVIIth International conference on Ultrarelativistic Heavy Ion interaction (QM2018) conference that ended last week. The new results were shown in the measurement of particle correlations, hard probes, small systems and new facilities. Some findings make us reassess already known facts from the new point of view.

"'Electroweak probes in heavy ion interactions with ATLAS"
David Izraeli
Tel-Aviv University
Abstract: Electroweak probes in heavy ion interactions with ATLAS Electroweak bosons produced in collisions of heavy ions provide an excellent tool to measure the initial stage of the heavy ion interaction. By measuring yields and distributions of the massive electroweak (EW) bosons via their leptonic decays and isolated prompt photons, we can assess the parton distribution functions and test their modifications in the nuclear environment compared to the ones of the free nucleon. Production rates of EW bosons is an opportunity to test our understanding of the collision geometry. EW probes serve as a standard candle for the calibrated measure of the jet energy loss in the strongly coupled quark-gluon plasma created in collisions of heavy ions. The ATLAS experiment at the LHC collected a high-statistics data sample in proton-proton, proton-nucleus and nucleus-nucleus collisions at the center-of-mass energies of 5.02 and 8.16 TeV. This talk will cover the most recent results and future perspectives for measuring the above-mentioned signatures and comparisons of results with various theoretical models.

LOCATION: The next  Nuclear Physics Joint Seminar for this year will be held on Monday, May 28th, at the Weizmann Institute of Science, Weissman Building (Physics) in the Drori Seminar room.
