    Title: Hadron formation in the deconfined matter at RHIC and LHC
    Author: Bellwied, Rene
    Subject: High Energy Physics - Phenomenology ; Nuclear Experiment ; Nuclear Theory
    Description: We have studied the probability of two succinct particle production mechanisms, likely to occur in the transition from the deconfined medium produced in RHIC and LHC heavy ion collisions back to the hadron gas, which is abundant at lower temperatures. Evidence has been found for in-medium fragmentation of non-equilibrated partons in the deconfined medium as well as bound state formation in the quark-gluon phase itself, as described by lattice QCD . Through the comparison to PNJL model calculations we attempt to quantify an extended phase of mixed degrees of freedom in a temperature range just above the QCD transition temperature. The extracted hadron formation probabilities exhibit flavor and baryon number dependencies, which are experimentally verifiable. We confront the calculations of the non-equilibrium and equilibrium particle production in heavy ion collisions with measurements from RHIC and LHC. Comment: 6 pages, 5 figures, Proceedings of the 50th International Winter Meeting on Nuclear Physics, 23-27 January 2012, Bormio, Italy

    Title: Quantum entanglement in the initial and final state of relativistic heavy ion collisions
    Author: Bellwied, Rene
    Subject: Nuclear Theory ; High Energy Physics - Phenomenology ; Nuclear Experiment
    Description: The possibility of quantum entanglement leading to a seemingly thermal distribution of the initial partonic state that maps to the final hadronic state in the evolution of the deconfined phase generated in relativistic heavy ion collisions is discussed in the context of early thermalization and final state particle distributions obtained in experiments at RHIC and the LHC. Comment: 6 pages, no figures, proceedings to the 34th Winter Workshop on Nuclear Dynamics (WWND 2018)

    Title: 27th winter workshop on nuclear dynamics (wwnd 2011)
    Author: Bellwied, Rene; Pruneau, Claude
    Description: These are the proceedings of the 27th edition of the Winter Workshop on Nuclear Dynamics, which was held in Winter Park, Colorado. As in previous years, the unique character of this conference series has allowed us to bring nuclear scientists from very different fields together to discuss their scientific achievements. At the high-energy frontier very exciting results from the first heavy-ion collisions at the LHC were shown. At the lower energies the RHIC beam energy scan is underway to span the gap between the SPS and RHIC and search for critical phenomena in the nuclear matter phase diagram. The nuclear structure and astrophysics communities have started to construct dedicated facilities at Michigan State University (F-RIB) and the GSI in Germany (FAIR). Theory is progressing across all these different energy regimes, and the new data, in particular from the LHC and RHIC, are motivating more detailed modeling and a deeper understanding of the underlying physics. These proceedings of the 27th Winter Workshop on Nuclear Dynamics again provide a snapshot of the status of the field. The articles, many of which are written by some of the most promising young scientists in the field, are conveying the feeling of excitement that permeates all subfields of nuclear science.

    Title: ALICE EMCal Physics Performance Report
    Author: Bellwied, Rene
    Subject: Physics - Instrumentation And Detectors ; High Energy Physics - Experiment ; Nuclear Experiment
    Description: The ALICE detector at the LHC (A Large Ion Collider Experiment) will carry out comprehensive measurements of high energy nucleus-nucleus collisions, in order to study QCD matter under extreme conditions and the phase transtion between con\"ined matter and the Quark-Gluon Plasma (QGP). This report presents our current state of understanding of the Physics Performance of the large acceptance Electromagnetic Calorimeter (EMCal) in the ALICE central detector. The EMCal enhances ALICE's capabilities for jet measurements. The EMCal enables triggering and full reconstruction of high energy jets in ALICE, and augments existing ALICE capabilities to measure high momentum photons and electrons. Combined with ALICE's excellent capabilities to track and identify particles from very low pT to high pT, the EMCal enables a comprehensive study of jet interactions in the medium produced in heavy ion collisions at the LHC.

    Title: Editors' preface
    Author: Bellwied, Rene; Lacey, Roy; Pratt, Scott
    Description: These are the proceedings of the 26th edition of the Winter Workshop on Nuclear Dynamics. As in previous years the unique character of this conference series has allowed us to bring nuclear scientists from very different fields together to discuss their scientific achievements. At the high-energy frontier results from the first elementary collisions at the LHC were shown. At the lower energies the RHIC beam energy scan is underway to span the gap between the SPS and RHIC and search for critical phenomena in the nuclear matter phase diagram. RHIC is at its peak of scientific output and many of the measurements and theories discussed here will serve as a roadmap for new measurements at the LHC and at the lower RHIC energies. The nuclear structure and astrophysics communities have started to construct dedicated facilities at Michigan State University (F-RIB) and the GSI in Germany (FAIR). These proceedings of the 26th Winter Workshop on Nuclear Dynamics again provide a snapshot of the status of the field. The articles, many of which are written by some of the most promising young scientists in the field, are conveying the feeling of excitement that permeates all subfields of nuclear science.
