The 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...

The 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...

Plenary Contribution
New 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...

We 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...

Plenary Contribution
The 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...

Data 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 $K^-$...

Recently, 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...

The $K^-_{stop} A$ $\rightarrow$ $\Sigma^\pm\pi^\mp A'$ 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...
