1WC.00001: Results from the heavy ion program at RHIC and expectations for the LHC Invited Speaker: Rene Bellwied I will review the latest results from the heavy ion program at RHIC in light of predictions and expectations for the LHC heavy ion program. New results from STAR and PHENIX will be presented which focus on the features that were also addressed in the first running period of PbPb collisions at the LHC as presented at the Quark Matter 2011 conference. These include particle correlation measurements, flow measurements, quarkonia measurements, jet measurements, the determination of initial conditions, and RHIC beam energy scan results.

1WC.00002: First Results from ALICE Invited Speaker: Helen Caines After nearly 20 years of preparations, first collisions at the LHC commenced in 2009. Since then proton beams have been collided at sqrt(s) = 0.9, 2.76 and 7 TeV, with the majority of the data being recorded at 7 TeV. In the Fall of 2010 another new era was entered when Pb-Pb collisions at 2.76 TeV were also delivered. ALICE's (A Large Ion Collider Experiment) main focus is on exploring the physics of strongly interacting matter created in these events. However, the pp data is also being investigated producing both intriguing new results, and serving as a baseline from which to compare the Pb-Pb data. I will present recent results from ALICE (A Large Ion Collider Experiment)from both the 2010 Pb-Pb run and the ongoing physics analyzes of the pp data. These first Pb-Pb results are broadly consistent with expectations based on lower energy RHIC and SPS data. They indicate that matter created in these collisions, while initially much larger and hotter, still behaves like a very strongly interacting, almost perfect liquid. [Preview Abstract] |

1WC.00003: Soft and Hard Probes of Lead+Lead Collisions at the LHC with the ATLAS Detector Invited Speaker: Brian Cole Heavy ion collisions at the LHC provide an opportunity to study the properties of strongly interacting matter at the highest temperatures ever created in the laboratory. The ATLAS detector with its large acceptance calorimetry, extensive silicon tracking, and large-acceptance muon spectrometers is well suited to study both soft/collective observables and high-$p_T$/hard observables in Lead+Lead collisions. ATLAS accumulated about 8~$\mu b^{-1}$ of data during the Fall 2010 LHC heavy ion run. Results will be presented from the analysis of that data set on charged particle multiplicity and pseudo-rapidity distributions, charged particle elliptic and higher harmonic collective flow, single charged particle spectra and single particle suppression at high $p_T$, single jet and dijet production, and W, Z, and single muon production.
