Fluid dynamical prediction of changed v1-flow at energies available at the CERN Large Hadron Collider

Substantial collective flow is observed in collisions between lead nuclei at Large Hadron Collider (LHC) as evidenced by the azimuthal correlations in the transverse momentum distributions of the produced particles. Our calculations indicate that the global v1-flow, which at RHIC peaked at negative rapidities (named third flow component or antiflow), now at LHC is going to turn toward forward rapidities (to the same side and direction as the projectile residue). Potentially this can provide a sensitive barometer to estimate the pressure and transport properties of the quark-gluon plasma. Our calculations also take into account the initial state center-of-mass rapidity fluctuations, and demonstrate that these are crucial for v1 simulations. In order to better study the transverse momentum flow dependence we suggest a new"symmetrized" vS1(pt) function, and we also propose a new method to disentangle global v1 flow from the contribution generated by the random fluctuations in the initial state. This will enhance the possibilities of studying the collective Global v1 flow both at the STAR Beam Energy Scan program and at LHC.

CERN-MEDICIS: une nouvelle infrastructure pour la production de radioisotopes a usage medical [CERN-MEDICIS (Medical Isotopes Collected from ISOLDE): a new facility].

CERN-MEDICIS (Medical Isotopes Collected from ISOLDE) est une plateforme de recherche destinée à la production de radioisotopes biomédicaux. Inauguré en 2014, il produira progressivement un nombre croissant de radioisotopes grâce au faisceau de protons ISOLDE déjà existant. Ce projet réunit des spécialistes du cancer, des chirurgiens, des experts en médecine nucléaire, en radiochimie et radiopharmacie et les scientifiques du CERN. Les radioisotopes ainsi produits seront destinés à la recherche fondamentale contre le cancer, à des études précliniques ainsi qu'au développement de protocoles d'imagerie et de thérapie destinés aux patients.Le CERN, les HUG, le CHUV, l'ISREC et l'EPFL qui soutiennent ce projet seront les premiers bénéficiaires de ces radioisotopes novateurs dont la distribution sera ensuite étendue à d'autres centres européens. CERN-MEDICIS is a facility dedicated to research and development in life science and medical applications. The research platform was inaugurated in October 2014 and will produce an increasing range of innovative isotopes using the proton beam of ISOLDE for fundamental studies in cancer research, for new imaging and therapy protocols in cell and animal models and for preclinical trials, possibly extended to specific early phase clinical studies (phase 0) up to phase I trials. CERN, the University Hospital of Geneva (HUG), the University Hospital of Lausanne (CHUV), the Swiss Institute for Experimental Cancer (ISREC) at Swiss Federal Institutes of Technology (EPFL) that currently support the project will benefit of the initial production that will then be extended to other centers.
