Dr Emanuele Vincenzo Pagano (LNS-INFN)27/01/2017, 17:00Short ContributionIn Heavy Ion Collisions (HIC) at Fermi energies (10 MeV/nucleon ≤ E/A ≤ 100 MeV/nucleon) hot nuclear systems are produced and they may disassemble by a variety of dynamical and statistical mechanisms with vastly different time scales (neck emission, fission, multifragmentation, fusion-evaporation, ecc.). The space-time sensitivity of the fragment-fragment Correlation Function to the...Go to contribution page

Ms Joana Wirth (TU München)27/01/2017, 17:20Short ContributionThe production and properties of $K^0_S$, $K^+$, $\Phi$ and $K^-$ in cold nuclear matter generated in pion-nucleon reactions ($\pi^- + A$, $A = C, W$) at $p_{\pi^-}= 1.7$ GeV/c has been investigated with the HADES detector at GSI. Similar to the $K^0$ production at the surface of the nuclei ($\sigma \sim A^{b}, b=2/3$), as already verified by the FOPI collaboration, it was assumed to apply...Go to contribution page

Dr Axel Schmidt (MIT)27/01/2017, 18:00Short ContributionOver the past two decades, a discrepancy has emerged between two different techniques for measuring the proton's electromagnetic form factors. Unpolarized electron-proton cross section measurements paint a picture of the proton's internal structure that is incompatible with measurements from polarization transfer experiments. The leading hypothesis is that the discrepancy is caused by a...Go to contribution page

Prof. Georg Wolschin (U Heidelberg)27/01/2017, 18:20Short ContributionThe suppression of Y mesons in the hot quark-gluon medium (QGP) versus reduced feed-down is investigated in UU collisions at RHIC energies and PbPb collisions at LHC energies. Our centrality- and p_T-dependent model encompasses screening, collisional damping and gluodissociation in the QGP. For Y(1S) it is in agreement with both STAR and CMS data provided the relativistic Doppler effect and...Go to contribution page

Dr Ulrich Müller (Inst. für Kernphysik, Univ. Mainz)27/01/2017, 18:40Short ContributionA measurement of the ratio $P_x/P_z$ of polarization transfer components in the $\mathrm{D}(\vec{e},e'\vec{p})n$ reaction at different missing momenta will be reported. The $P_x/P_z$ ratio observed for H, D, and $\mathrm{^{4}He}$, respectively, indicates a dependency on the proton's virtuality and the missing momentum direction, but not the average nuclear density.Go to contribution page
