307. Quarkonia in nuclear collisions

Dr Elena Ferreiro (Universidad de Santiago de Compostela)

03/09/2018, 14:30

Quarkonium has been regarded as one of the golden probes to identify the phase transition from confined hadronic matter to the deconfined quark-gluon plasma (QGP) in heavy-ion collisions. Recent theoretical developments in the study of the J/ψ and ϒ families at the energies of Large Hadron Collider (LHC) are reviewed. In particular, the possible implications related to the production and...

302. Probing hot QCD matter in ultrarelativistic heavy-ion collisions

Alice Ohlson (Yale University)

03/09/2018, 14:55

In high-energy collisions of heavy nuclei, the resulting state of matter attains such high temperatures and energy densities that quarks and gluons are no longer confined into hadrons. Known as the quark-gluon plasma (QGP), this matter occupies the high-temperature and high-density regime of the phase diagram of quantum chromodynamics (QCD). By probing the properties of the QGP, we are able...

136. Acceleration of High-Brightness Heavy Ion Beams for Research into Heavy Ion Nuclear Physics

Prof. Boris Sharkov (JINR Dubna)

03/09/2018, 15:20

This presentation outlines ongoing activities on development of heavy ion accelerator facilities, providing high-brightness beams capable of generating intense beams of RI as well as extreme state of nuclear matter. Manifested facilities goals is pushing the “intensity” and the “precision frontiers” to the extremes when accelerating full range of ion beam species from p+ to U to highest beam...

142. Perspectives of QCD phase diagram studies with the CBM experiment at FAIR

Dr Maksym Zyzak (GSI Helmholtzzentrum für Schwerionenforschung GmbH)

03/09/2018, 15:38

The future heavy ion experiment CBM at the FAIR facility will study the QCD phase diagram in the region of high baryon chemical potential at relatively moderate temperatures, where a complex structure is predicted by modern theories. In order to detect possible signatures of this structures, the physics program of the experiment includes a comprehensive study of the extremely rare probes like...

91. Study of quarkonium production in p-A and AA collisions with ALICE at the LHC

Gabriele Gaetano Fronzé (TO)

03/09/2018, 15:56

ALICE (A Large Ion Collider Experiment) is devoted to the study of heavy-ion collisions at the CERN Large Hadron Collider (LHC). It is predicted that a deconfined state of hadronic matter, the Quark-Gluon Plasma (QGP), is created at the large energy densities reached in such collisions. The production of heavy quarkonium (ccbar and bbar bound states) appears modified in the presence of a QGP,...

97. Heavy-flavour production measurements in heavy-ion collisions with ALICE at the LHC

Dr Andrea Festanti (CERN)

03/09/2018, 16:14

Heavy quarks are effective probes of the properties of the Quark-Gluon Plasma (QGP) created in ultra-relativistic heavy-ion collisions. Charm and beauty quarks are produced in hard scattering processes on timescales shorter than the QGP formation time due to their large masses and, thus, they experience the entire evolution of the medium interacting with its constituents via in-medium gluon...

306. Results on quarkonia and its associated production with ATLAS

Dr Evelina Bouhova-Thacker (Lancaster University)

03/09/2018, 16:32

The associated production of vector boson with quarkonia is a key observable for understanding the quarkonium production mechanisms, including the separation of single and double parton scattering components. This talk will present the latest differential measurements from ATLAS of (associated) quarkonium production.

308. The characterisation of the Quark Gluon Plasma

Prof. Raimond Snellings (Utrecht University)

04/09/2018, 17:00

66. New results on Coulomb interaction effects in relativistic heavy ion collisions

Dr Oana Ristea (University of Bucharest, Faculty of Physics)

04/09/2018, 17:25

In heavy-ion collisions, the differences in shape between the positive and negative pion transverse momentum spectra at low pT can be used to study the Coulomb final-state interaction. The produced charged particles are moving in a Coulomb field generated by the positive net-charge of the stopped participant protons. The charged pions, as the most abundantly produced and lightest species, are...

101. Light-Flavor Hadron Production from Small to Large Collision Systems at ALICE

Dr Anders Knospe (The University of Texas at Austin)

04/09/2018, 17:43

Light-flavor hadrons, which consist of up, down, and strange valence quarks, can be used to study many different properties of ion-ion collisions. An overview of light-flavor hadron measurements performed with the ALICE detector will be presented, including measurements in pp collisions from 0.9 to 13 TeV, p-Pb collisions at 5.02 and 8.16 TeV, Pb-Pb collisions at 2.76 and 5.02 TeV, and new...

102. Light (anti-)nuclei and (anti-)hypernuclei production with ALICE at the LHC

Dr Stefano Piano (TS)

04/09/2018, 18:01

The high energy pp, p-Pb, and Pb-Pb collisions at the LHC offer a unique opportunity to study the production mechanisms of light nuclei, their corresponding anti-nuclei and hyperon-baryon bound systems, called hypernuclei. Measurements at different energies and with various system sizes allow to constrain the models of the production mechanisms of light flavour baryon clusters, in particular...

115. LHCb Heavy-ion results in collider and fixed-target mode

Mr Luciano Libero Pappalardo (FE)

04/09/2018, 18:20

LHCb is a fully instrumented forward spectrometer at the LHC with a pseudorapidity coverage 2<eta<5 designed for the study of hadrons containing b and c-quarks in pp collisions. The forward acceptance and its instrumentation for high-precision vertex reconstruction, tracking and particle identification allow for unique studies in heavy-ion collisions. Furthermore, a system for noble gas...
