“…On the basis of lattice calculations, we require the existence of a deconfined quark matter region (0<a/sub s/<1) beyond the hadron gas phase, which goes asymptotically into the ideal quark-gluon plasma domain, in the phase diagram of nuclear matter. …”

“…The main goal of the experiment is to observe and study the phase transition from hadronic matter to deconfined partonic matter (quark gluon plasma - QGP). ALICE is conceived as a general purpose detector and will address most of the phenomena related to the QGP formation at LHC energies: to this purpose, a large fraction of the hadrons, leptons and photons produced in each interaction will be measured and identified. (18 refs).…”

“…The searc h only mak es use of the kinematic signature of Higgs- strahlung events, and thus, is sensitiv e to all events in which the Higgs boson h 0 decays into quark pairs of arbitrary avour or into gluon pairs. In con trast to searches for the Standard Model Higgs boson, which are sensitive only to h0 -> bb (and h0 -> T+T-), this search remains sensitive in models, such as Two-Higgs-Doublet-models, in which the branching ratio into b quarks is suppressed for certain mo del parameters. …”

“…From azimuthal distributions of protons and pi sup - mesons the out-of-plane (squeeze-out) flow effects have been observed and the parameter a sub 2 (the measure of the anisotropic emission strength) has been extracted. The Quark-Gluon String Model reproduces quite well the experimental results…”

“…QCD works, new NNLO calculations are becoming available and new string calculational tools are emerging, but no conclusions can yet be drawn about the discovery of the quark-gluon plasma or pentaquarks. The small upward shift in the experimental value of m_t raises somewhat the central value of the Higgs mass extracted from a global electroweak fit, and the CKM model describes well the data from the B factories. …”

While H can be approached using measurements of electroproduction cross sections, asymmetry measurements in hard exclusive meson production off transversely polarized targets can help to constrain the GPD E and chiral-odd GPDs. …”
