Mr Andrey Polyanskiy (Institut für Kernphysik, Forschungszentrum Jülich)10/11/11, 2:30 PMHadron PhysicsParallel ContributionThe production of phi-mesons in collisions of 2.83 GeV protons with C, Cu, Ag and Au nuclear targets has been measured with the ANKE magnetic spectrometer at the Cooler Synchrotron COSY. The phi was detected at small angles via its K+K- decay branch. The measured target mass dependence of the production cross section can be related to the in-medium phi width. Comparisons with three...Go to contribution page

Dr Marco Destefanis (Universita' degli Studi di Torino and INFN)10/11/11, 2:55 PMHadron PhysicsPlenary ContributionThe physics program of the future PANDA experiment includes the investigation of the non-perturbative region of the QCD by mean of antiproton beams, eventually polarised, with a beam momentum up to 15 GeV/c. Part of the PANDA spectrometer is devoted to the muon identification, that allow to access many among those processes needed to probe the nucleonic structure. The high foreseen luminosity...Go to contribution page

Prof. Vladimir Nedorezov for the GRAAL collaboration (INR RAS Moscow Russia)10/11/11, 3:20 PMHadron PhysicsPlenary ContributionNew precise experimental data on total photo-absorption cross sections are given for hydrogen, deuterium and carbon nuclei in the energy range from 0.75 to 1.5 GeV (see Figure). Measurement was performed with the back scattered tagged gamma beam (GRAAL facility at ESRF) and large acceptance detector LAGRANgE. The hadron contribution was obtained subtracting the background from the total...Go to contribution page

Mr Wojciech Krzemien (Jagiellonian University)10/11/11, 3:45 PMHadron PhysicsPlenary ContributionWe conduct a search for the 4He-eta bound state with WASA-at-COSY facility, via a measurement of the excitation functions for the dd -> 3-He p pi- reaction, where the outgoing p-pi pairs originate from the conversion of the eta meson on a nucleon inside the He nucleus. In June, 2008 first measurements of the excitation functions for the dd -> 3He p pi reaction were performed. In the...Go to contribution page

Dr Pia Thörngren Thörngren Engblom (Università di Ferrara;Royal Institute of Technology, Stockholm)10/11/11, 4:40 PMHadron PhysicsPlenary ContributionThe rich kinematical region in proton deuteron breakup reactions at low to intermediate energy offers a versatile laboratory for the chiral effective field theory, the modern theory of nuclear forces. Presently the spin structure of the three nucleon continuum exhibit disparate results when comparing experimental data to theoretical predictions based on two-nucleon potentials either with or...Go to contribution page

Dr Alessandra Filippi (TO)10/11/11, 5:05 PMNuclear PhysicsPlenary ContributionData on two-nucleon K^- absorption in mesonless final states, $K^- + N + N\rightarrow Y N$, are very scarce and dated. Most of the existing capture rates have been inferred indirectly from mononucleonic absorptions, and only results for $^4$He, $^{12}$C, Ne and CF$_3$Br exist, obtained by bubble chamber experiments [1]. The general understanding is that pionless two-nucleon $K^-$...Go to contribution page

Mr Patrik Adlarson (Uppsala Universitet)10/11/11, 5:30 PMHadron PhysicsPlenary ContributionRecently, a large statistics sample of approximately 3*10^7 decays of the eta meson have been collected with the WASA detector at COSY using the pd ->3He reaction at beam kinetic energy 1 GeV. This data are being used to study the not so rare eta decays involving charged pions, like pi+ pi- pi0 . This decay proceeds mainly via a strong isospin violating contribution, where the decay width...Go to contribution page

Prof. Paolo Camerini (Univ. Trieste & INFN Trieste)10/11/11, 5:55 PMHadron PhysicsParallel ContributionThe $K^-_{stop} A$ $\rightarrow$ $\Sigma^\pm\pi^\mp A'$ reaction is studied on light nuclei, $A=$ $^{6,7}Li$, $^9Be$, $^{13}C$ and $^{16}O$. The outgoing $\Sigma$'s and $\pi$'s are detected using the FINUDA spectrometer, which operated at the DA$\Phi$NE $e^+e^-$ facility (LNF). The $\Sigma^\pm$ hyperons are reconstructed via the $n \pi^\pm$ decay with the neutrons detected by...Go to contribution page
