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…
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…
Proton, deuteron and triton flow measurements in Au+Au collisions at GeV
HADES collaboration, J. Adamczewski-Musch, O. Arnold +102
High precision measurements of flow coefficients () for protons, deuterons and tritons relative to the first-order spectator plane have been performed in Au+Au c…
Spheroidal expansion and freeze-out geometry of heavy-ion collisions in the few-GeV energy regime
Szymon Harabasz, JÄdrzej KoÅaÅ, RadosÅaw Ryblewski +6
A spheroidal model of the expansion of hadronic matter produced in heavy-ion collisions in the few-GeV energy regime is proposed. It constitutes an extension of the spherically sym…
