  • Advances in Quark Gluon Plasma
    Advances in Quark Gluon Plasma Gin´esMart´ınez Garc´ıa SUBATECH, CNRS/IN2P3, Ecole´ des Mines de Nantes, Universit´ede Nantes, 4 rue Alfred Kastler, 44307 Nantes, France (Dated: April 5, 2013) In the last 20 years, heavy-ion collisions have been a unique way to study the hadronic matter in the laboratory. Its phase diagram remains unknown, although many experimental and theoretical studies have been undertaken in the last decades. After the initial experiences accelerating heavy nuclei onto fixed targets at the AGS (BNL, USA) and the SPS (CERN, Switzerland), the Relativistic Heavy Ion Collider (RHIC) at BNL was the first ever built heavy-ion collider. RHIC delivered its first collisions in June 2000 boosting the heavy-ion community. Impressive amount of experimental results has been obtained by the four major experiments at RHIC: PHENIX, STAR, PHOBOS and BRAHMS. In November 2010, the Large Hadron Collider (LHC) at CERN delivered lead-lead collisions at unprecedented center-of- mass energies, 14 times larger than that at RHIC. The three major experiments, ALICE, ATLAS and CMS, have already obtained many intriguing results. Needless to say that the heavy-ion programs at RHIC and LHC promise fascinating and exciting results in the next decade. The first part of the lectures will be devoted to introduce briefly the QCD descrip- tion of the strong interaction (as part of the Standard Model of Particle Physics) and to remind some basic concepts on phase transitions and on the phase diagram of matter. In the second part, I will focus on the properties of matter at energy densities above ≈1 GeV/fm3.

  • CERN Achievements in Relativistic Heavy Ion Collisions, Hence Covering a Period of Time That Dates Back to 1980
    EPJ Web of Conferences 95, 06001 (2015) DOI: 10.1051/epjconf/20159506001 C Owned by the authors, published by EDP Sciences, 2015 , GiuseppeEugenioBruno1 a 1DipartimentoInterateneodiFisica‘M.Merlin’andSezioneINFN,Bari,Italy Abstract. Twenty years after a Letter of Intent by the GSI and LBL groups for the “Study of particle production and target fragmentation in central 20Ne on Pb reactions, at 12 GeV per nucleon energy of the CERN PS external beam" [1], based on the results found by the NA45/CERES, NA49, NA50, and WA97/NA57 experiments at the SPS, CERN announced compelling evidence for the formation of a new state of matter in heavy- ion collisions at CERN-SPS energies [2]. Some of the experiments were indeed the 2nd or 3rd generation successors of the apparatuses originally proposed by the GSI-LBL collaboration. Actually, the CERN ion program initiated at the SPS with the acceleration of oxygen ions at 60 and 200 GeV/nucleon only in 1986, and continued with sulphur ions at 200 GeV/nucleon up to 1993. The rest is history: lead-ion beams at 160 GeV/nucleon became available at the SPS in 1994; the√ LHC accelerated and collided lead beams at a center of mass energy per nucleon pair sNN = 2.76 TeV in 2010. Heavy ion physics is definitely in the future program of CERN: ALICE will operate a major upgrade of its detectors during the second long shutdown of the LHC, in 2018-2019, and the associated physics program will span the third and fourth LHC runs, till late 2020s. 1 Foreword I was CERN summer student in 1998, and I have been asked to report on the CERN Achievements in Relativistic Heavy Ion Collisions, hence covering a period of time that dates back to 1980.

  • Open Charm Measurements at CERN SPS Energies with the New Vertex Detector of the NA61/SHINE Experiment: Status and Plans †
    universe Article Open Charm Measurements at CERN SPS Energies with the New Vertex Detector of the NA61/SHINE Experiment: Status and Plans † Anastasia Merzlaya 1,2,* and on behalf of the NA61/SHINE Collaboration 1 Faculty of Physics, Astronomy and Applied Computer Science, Jagiellonian University, 31-007 Krakow, Poland 2 Faculty of Physics, Saint Petersburg State University, 199034 Saint Petersburg, Russia * Correspondence: [email protected] † This paper is based on the talk at the 7th International Conference on New Frontiers in Physics (ICNFP 2018), Crete, Greece, 4–12 July 2018. Received: 30 November 2018; Accepted: 26 December 2018; Published: 4 January 2019 Abstract: The study of open charm meson production provides an efficient tool for detailed investigations of the properties of hot and dense matter formed in nucleus-nucleus collisions. The interpretation of the existing data from the CERN Super Proton Synchrotron (SPS) suffers from a lack of knowledge about the total charm production rate. To overcome this limitation, the heavy-ion program of the NA61/SHINE experiment at the CERN SPS has been upgraded to allow for precise measurements of particles with a short lifetime. A new vertex detector (Small Acceptance version of the Vertex Detector (SAVD)) was constructed to meet the challenges of open charm measurements in nucleus-nucleus collisions. The first exploratory data taking of Pb + Pb collisions at 150A GeV/c with the SAVD was performed in 2016, and a D0 signal was extracted in its D0 ! p+ + K− decay channel. This was the first, direct observation of open charm in nucleus-nucleus collisions at the SPS energies.

  • Ultra-Relativistic Nuclear Collisions at CERN
    June 16, 2015 15:44 60 Years of CERN Experiments and Discoveries – 9.75in x 6.5in b2114-ch03 page 61 Toward the Limits of Matter: Ultra-relativistic Nuclear Collisions at CERN Jurgen Schukraft1 and Reinhard Stock2 1CERN, CH-1211 Geneva 23, Switzerland [email protected] 2FIAS, 60438 Frankfurt am Main, Germany [email protected] Strongly interacting matter as described by the thermodynamics of QCD undergoes a phase transition, from a low temperature hadronic medium, to a high temperature quark–gluon plasma state. In the early universe this transition occurred during the early microsecond era. It can be investigated in the laboratory, in collisions of nuclei at relativistic energy, which create “fireballs” of sufficient energy density to cross the QCD phase boundary. We describe three decades of work at CERN, devoted to the study of the QCD plasma and the phase transition. From modest beginnings at the SPS, ultra- relativistic heavy ion physics is today a central pillar of contemporary nuclear physics and forms a significant part of the LHC programme. 1. Strongly Interacting Matter We recall here the development of a novel research field at CERN, devoted to the phases, and phase structure of matter governed by the strong fundamental force. Its proper field theory was discovered around 1970: Quantum Chromodynamics (QCD) addresses the fundamental interactions of elementary quarks, as mediated by gluons. Importantly,the gluons carry strong charges themselves, unlike the uncharged photons that mediate the QED interaction. Thus QCD is a much more complicated theory, mathematically. Both these field theories constitute a part of the modern Standard Model of elementary interactions.
