Recent results from HADES on electron pair production in relativistic heavy-ion collisions (2009)
Agakishiev, G., Balanda, A., Belver, D., Belyaev, A. V., Blanco, A., ...
Systematic investigations of dilepton production are performed at the SIS accelerator of GSI with the HADES spectrometer. The goal of this program is a detailed understanding of di-electron emission...
Origin of the low-mass electron pair excess in light nucleus-nucleus collisions (2009)
Balanda, A., Belver, D., Belyaev, A. V., Blanco, A., Böhmer, M., ...
We report measurements of electron pair production in elementary p+p and d+p reactions at 1.25 GeV/u with the HADES spectrometer. For the first time, the electron pairs were reconstructed for n+p...
Deep sub-threshold $\Xi^-$ production in Ar+KCl reactions at 1.76A GeV (2009)
Agakishiev, G., Balanda, A., Bassini, R., Belver, D., Belyaev, A. V., Blanco, A., ...
We report first results on a deep sub-threshold production of the doubly strange hyperon $\Xi^-$ in a heavy-ion reaction. At a beam energy of 1.76A GeV the reaction Ar+KCl was studied with the High...
The High-Acceptance Dielectron Spectrometer HADES (2009)
Balanda, A., Bannier, B., Bassini, R., Belver, D., Belyaev, A. V., ...
HADES is a versatile magnetic spectrometer aimed at studying dielectron production in pion, proton and heavy-ion induced collisions. Its main features include a ring imaging gas Cherenkov detector...
Phi decay: a relevant source for K- production at SIS energies? (2009)
Balanda, A., Bannier, B., Bassini, R., Belver, D., Belyaev, A. V., ...
We present phase space distributions and multiplicities of K+, K- and phi mesons produced in Ar+KCl reactions at a kinetic beam energy of 1.756 AGeV and measured with the HADES spectrometer. The...
