Dielectron production in C-12+C-12 collisions at 2 A GeV with HADES
Original language description
We report on a measurement of electron pair production in C-12+C-12 collisions at an incident energy of 2 GeV per nucleon with the HADES spectrometer. The measured pair production probabilities span over five orders of magnitude from the pi(0)-Dalitz tothe rho/omega invariant-mass region. Dalitz decays of pi(0) and account for all the yield up to 0.15 GeV/c(2), but for only about 50% above this mass. The excess yield is in agreement with the former DLS result if one assumes that it scales with beam energy like pion production. A preliminary analysis of C-12+C-12 collisions at an incident energy of 1 A GeV, measured with the HADES detector, supports this scenario.

Měření produkce elektronových párů při incidentní energii 2GeV na nukleonu. Pravděpodopnost produkce se mění v rozsahu 5 řádů od oblasti hmotnosti pi(0)do rho /omega.Daliknův rozpad pi(0)vysvětluje celý výtěžek do 0,15GeV/c(2),ale jen 50% jejich hmotnosti.
