Study of electromagnetic processes with the dielectron spectrometer HADES
Résumé
Dielectron production in pp and dp reactions at 1.25 A.GeV has been studied with the High Acceptance DiElectron Spectrometer (HADES) at GSI. Results obtained in inclusive and exclusive channels are shown, along with π+, π− and η production in pp reactions at 1.25 and 2.2 GeV. Perspectives of experiments with π− beams are outlined.
