M. Federico Scozzi (IPN Orsay)11/05/2016 10:45Nuclear PhysicsOral PresentationThe High-Acceptance Di-Electron Spectrometer (HADES) operates at the GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt with pion, proton and heavy-ion beams provided by the synchrotron SIS18. HADES results on e$^+$e$^-$ production in proton-nucleus reactions and in nucleus-nucleus collisions demonstrate a strong enhancement of the dilepton yield relative to a reference spectrum...Aller à la page de la contribution

Mlle ying wang (Institut de Physique Nucléaire Orsay)11/05/2016 11:00Nuclear PhysicsOral PresentationExclusive binary annihilation reactions induced by antiprotons of momentum from 1.5 to 15 GeV/c can be extensively investigated at FAIR/PANDA [1]. We are especially interested in the channel of charged pion pairs. Whereas this very probable channel constitutes the major background for other processes of interest in the PANDA experiment, it carries unique physical information on the quark...Aller à la page de la contribution

Mlle Ani Simonyan (IPNO)11/05/2016 11:15Nuclear PhysicsOral PresentationThe Heavy Photon Search (HPS) is an experiment held in Jefferson Laboratory to search for new heavy vector boson(s) (A') in the mass range of 20 MeV/c2 to 1000 MeV/c2. Such heavy photons could couple to electrons and be radiated in electron scattering before decaying into narrow e+ e- resonances which can be observed above the QED background. The experimental setup is using a new compact,...Aller à la page de la contribution

M. Mohamad Tarhini (IPN Orsay)11/05/2016 11:30Nuclear PhysicsOral PresentationIn ultra-relativistic heavy-ion collisions, the formation of a hot and dense strongly-interacting medium, a Quark-Gluon Plasma (QGP), is expected. To characterize the QGP, one must disentangle genuine QGP effects from the ones due to the nuclear medium presence known as Cold Nuclear Matter (CNM) effects. One of the important CNM effects is the modification of the parton distribution function...Aller à la page de la contribution
