Book Description
This thesis provides a comprehensive view of the physics of charmed hadrons in high-energy proton-proton and heavy-ion collisions. Given their large masses, charm quarks are produced in the early stage of a heavy-ion collision and they subsequently experience the full system evolution probing the colour-deconfined medium called quark-gluon plasma (QGP) created in such collisions. In this thesis, the mechanisms of charm-quark in-medium energy loss and hadronisation are discussed via the measurements of the production of charm mesons with (Ds+) and without (D+) strange-quark content in different colliding systems, using data collected by the ALICE experiment at the CERN LHC. The participation of the charm quark and its possible thermalisation in the QGP are studied via measurements of azimuthal anisotropies in the production of D+ mesons. Finally, the prospects for future measurements with the upgraded ALICE experimental apparatus and with more refined machine learning techniques are presented.

Book Description
Central collisions between nuclei at relativistic energies form a hot and dense hadronic system over a large volume. Phenomenological models, as well as QCD calculations on the lattice, predict a phase transition in nuclear matter leading to deconfinement, a state of matter in which quarks and gluons are free to move inside the entire volume of the deconfined region. This new state was given the name of Quark Gluon Plasma (QGP). Based on the conjecture that collisions of heavy nuclei at high energies can create the necessary condition of a high energy density thermalized system, a series of experiments were built to search for possible signals of QGP creation. The NA35 collaboration uses a wide acceptance apparatus at the CERN SPS which detects the majority of charged hadrons (h{sup {+-}}), and neutral strange particles produced in reactions of p, 16O and 32S projectiles at 60 and 200 GeV/nucleon lab momentum on different targets. It consists of two major tracking devices which provide the momentum measurement of the charged particles: a 2 m long streamer chamber (SC) which is placed inside a 1.5 T vertex magnet, viewed by three cameras, and a 2.5x1.5x1.0 m3 Time Projection Chamber (TPC). A set of calorimeters was used as the basic trigger device of the experiment, to select central (small impact parameter) collisions. In the data presented here, a calorimeter placed in the beam path selects near head-on collisions, i.e. events where only a small amount of energy (mostly spectator nucleon energy) was detected in an angular acceptance of less than 0.3 degrees around the beam axis. The data sample consists of three systems: S+S, S+Ag and S+Au at 200 GeV/c with trigger cross section of 3, 3.2 and 6% of the total inelastic cross section, respectively.

Book Description
Articles focus on the planned European proton-proton collider, and concentrate on physics issues, rather than the more technical concerns addressed in the three previous workshops. The use of energies much higher than those of the American Superconducting Super Collider is featured. Topics include reviews of current projects, hadron collisions, lep

Book Description
This is a collection of exciting papers in the area of high energy nuclear collisions and quark gluon plasma. The volume covers lectures on the natures of hadronic matter at high temperature and/or density and signals of quark-hadron phase transitions. It also includes discussions and descriptions of the data of CERN and BNL nucleus-nucleus collisions. Other contributions deal with physics at RHIC, LHC and the PS-collider, collision simulators and various related topics.
