Physics Division Seminars bring us speakers on a variety of physics related subjects. Usually these are held in the Building 6008 large Conference Room, at 3:00 pm on the chosen day, but times and locations may vary. For more information, contact our seminar chairman,

Heavy quarks (charm and beauty) produced in the initial hard parton scatterings within heavy-ion collisions are an important tool to study the properties of the hot and dense, strongly coupled partonic medium - a quark-gluon plasma (QGP). The high energy partons traversing the QGP interact with the bulk of the medium and loose a fraction of their energy. Such a process depends on the properties of the medium but also on the mass and the color charge of the parton.
Within the ALICE detector the production of heavy quarks is studied by measuring the heavy-flavor hadrons or leptons from the semi-leptonic decays of hadrons containing heavy quarks over a wide momentum range. In particular, the Electromagnetic Calorimeter (EMCal) providing particle identification and triggering capabilities plays a central role in measurements of the semi-electronic channel of high-pT heavy-flavor hadrons at mid-rapidity.
In this talk an overview of measurements of heavy-flavor production in semi-electronic channels in different collision systems using ALICE detector will be provided. In addition, an outlook on the opportunities, but also on the challenges, in heavy flavor measurements with the upgraded detector during the high-luminosity LHC Run-3 (beyond 2019) will be discussed.
