Hyperon signatures in the PANDA experiment at FAIR / PANDA Collaboration
We present a detailed simulation study of the signatures from the sequential decays of the triple-strange pbar p -> Ω+Ω- -> K+ΛbarK- Λ -> K+pbarπ+K-pπ- process in the PANDA central tracking system with focus on hit patterns and precise time measurement. [...]

(L'Aquila U. ; INFN, Aquila) et al.
Presently under construction in Lund, Sweden, the European Spallation Source (ESS) will be the world's brightest neutron source. As such, it has the potential for a particle physics program with a unique reach and which is complementary to that available at other facilities. [...]

Estructura Materia) ; Cederkäll, J (CERN) ; Van Duppen, P (Leuven U.) ; Emhofer, S (Munich U., Neutron Group) ; Forstner, O (CERN) et al. /ISOLDE ; REX-ISOLDE
At the newly constructed postaccelerator REX-ISOLDE ( R adioactive beam Ex periment at ISOLDE) we have investigated reactions induced by a 9 Li beam incident on a deuterium target at an energy of 2.36 MeV/u. Most reaction channels were recorded. [...]

The excitation function of the proton resonance elastic scattering with a ^30Mg beam of 2.92 MeV/nucleon was measured around 0 degrees in the laboratory frame. Three resonances corresponding to high excited states in ^31Al were successfully observed. [...]

Feasibility studies of time-like proton electromagnetic form factors at PANDA at FAIR / PANDA Collaboration
The results of simulations for future measurements of electromagnetic form factors at \PANDA (FAIR) within the PandaRoot software framework are reported. The statistical precision at which the proton form factors can be determined is estimated. [...]

Studies of continuum states in${16}$ Ne using three-body correlation techniques / Marganiec, J ; Wamers, F ; Aksouh, F ; Aksyutina, Yu ; Alvarez-Pol, H ; Aumann, T ; Beceiro-Novo, S ; Boretzky, K ; Borge, M J G (CERN) ; Chartier, M et al.
Two-proton decay of the unbound $ T_{z} =-2$ nucleus$^{16}$Ne , produced in one-neutron knockout from a 500 MeV/u$^{17}$Ne beam, has been studied at GSI. The ground state, at a resonance energy 1.388(15) MeV, ( $ \Gamma =0.082(15)$ MeV) above the$^{14}$O +p+p threshold, and two narrow resonances at $ E_{r} =3.220(46)$ MeV and 7.57(6) MeV have been investigated.

Isobaric analog resonances of Mg31 and the border of the island of inversion / Imai, N ; Mukai, M ; Cederkäll, J ; Aghai, H (CERN) ; Golubev, P ; Johansson, H T ; Kahl, D ; Kurcewics, J (CERN) ; Teranishi, T ; Watanabe, Y X
The evolution of the nuclear shell structure in the region of the neutron-rich shell-breaking nucleus Mg32 has been the subject of considerable interest. We present here the first determination of the overlap of the ground and two first excited states in Mg31 with a neutron coupled to the ground state in Mg30 based on studies of its isobaric analog resonances in Al31.

Precision measurement of $\sigma(e^+e^-\rightarrow\pi^+\pi^-\gamma)/\sigma(e^+e^-\rightarrow \mu^+\mu^-\gamma)$ and determination of the $\pi^+\pi^-$ contribution to the muon anomaly with the KLOE detector / KLOE-2 Collaborations
We have measured the ratio $\sigma(e^+e^-\rightarrow\pi^+\pi^-\gamma)/\sigma(e^+e^-\rightarrow \mu^+\mu^-\gamma)$, with the KLOE detector at DA$\Phi$NE for a total integrated luminosity of $\sim$ 240 pb$^{-1}$. From this ratio we obtain the cross section $\sigma(e^+e^-\rightarrow\pi^+\pi^-)$. [...]
