First measurement of massive virtual photon emission from N* baryon resonances
R. Abou Yassine, J. Adamczewski-Musch, O. Arnold +127
First information on the time-like electromagnetic structure of baryons in the second resonance region has been obtained from measurements of dielectron (e+ e-) invariant-mass and…
Feasibility of the observation of mesic nuclei in the semi-exclusive C() reaction
Natsumi Ikeno, Yuko Higashi, Hiroyuki Fujioka +7
We study theoretically the feasibility of the semi-exclusive C() reaction for the observation of mesic nuclei using the microscopic transport model JAM.…
Formation and lifetime measurements of light hypernuclei in Ag+Ag collisions at = 2.55 GeV
R. Abou Yassine, J. Adamczewski-Musch, C. Asal +111
We present the first observation of and in Ag+Ag collisions at = 2.55 GeV, emitted around mid-rapidity. The hypernu…
Excitation Spectra of the Reaction near the -Meson Emission Threshold Measured in Coincidence with High-Momentum Protons
R. Sekiya, K. Itahashi, Y. K. Tanaka +74
The missing mass of the reaction has been measured near the -meson emission threshold in coincidence with a high-momentum proton to selectively collect $…
Polarization observables in double neutral pion photoproduction
TAPS Collaboration, T. Seifen, J. Hartmann +73
Measurements of target asymmetries and double-polarization observables for the reaction are reported. The data were taken with the CBELSA/TAPS experiment at the…
