“…In contrast to many other studies, the analysis concentrates not on the vector boson fusion but on the gluon fusion production mechanism. The backgrounds are mainly suppressed by requiring a large invariant mass of the Higgs boson and the balancing jet. …”

“…Elle sera l'occasion de faire le point et le bilan des avancées des diverses thématiques de recherche: boson de Higgs, les interactions électrofaibles, le quark top, la Supersymétrie, les saveurs lourdes, la violation de CP et le Plasma de Quarks et de Gluons. Elle sera aussi l'occasion de discuter des plans d'amélioration des détecteurs en vue des futures phases de fonctionnement du LHC ainsi que les perspectives pour la physique. …”

Strange baryon production is one of the essential observables to understand the mechanisms involved in the medium. …”

“…Measurements in proton-nucleus (p-A) collisions and their comparison with proton-proton (pp) collision results provide complementary information on nuclear effects that are present in the absence of the Quark-Gluon Plasma (QGP). In addition, the calculation of the production of charmonia in p-A collisions presents a challenging test of perturbative QCD at low scales "Q^2" and low fractional momentum of the involved partons. …”

“…--HTML--><p>The observation of a long-range, near-side, two-particle correlation (known as the ridge) has been over the past decade a key signature of the hydrodynamic evolution of the hot and strongly interacting matter produced in heavy-ion collisions. Indeed, the Quark-Gluon Plasma appears to behave as a perfect fluid and latest results from LHC experiments in Pb-Pb collisions at 2.76 and 5 TeV show a nice agreement with hydrodynamic expectations, either for inclusive charged hadrons or identified particles. …”
