First measurement of massive virtual photon emission from N* baryon resonances

R. Abou Yassine, J. Adamczewski-Musch, O. Arnold, E. T. Atomssa et autres

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 angular distributions in the quasi-free reaction $π-$ p $\rightarrow$ n e+ e- at $\sqrt{s_{πp}}$ = 1.49 GeV …

Hadron Production and Propagation in Pion-Induced Reactions on Nuclei

R. Abou Yassine, J. Adamczewski-Musch, O. Arnold, E. T. Atomssa et autres

Hadron production ($π^\pm$, proton, $Λ$, $K_S^0$, $K^\pm$) in $π^- + \mathrm{C}$ and $π^- + \mathrm{W}$ collisions is investigated at an incident pion beam momentum of $1.7~\mathrm{GeV}/c$. This comprehensive set of data measured with HADES at SIS18/GSI significantly extends the existing world data …
