Dilepton analysis in the HADES spectrometer for C-12+C-12 at 2 AGEV
Original language description
The identification of the light mesons in the HADES spectrometer is based on an invariant mass reconstruction of their decay into e(+)e(-) pairs. In the dilepton (e(+)e(-)) signal reconstruction, particularly important is the reduction of a huge combinatorial background arising from wrong combinations of e(+) and e(-) to unlike sign pairs. Methods of the dilepton signal and combinatorial background reconstruction in the HADES spectrometer will be presented.

Analyza dileptonu v spektrometru HADES pro C-12 + C-12 pri 2 AGeV
Czech description
Dielektronový spektrometr HADES začal pracovat v GSI Darmstadt. Fyzikální program spočívá ve studiu změn vlastností vektorových mezonů v jaderném médiu, pomocí jejich rozpadu na elektron a pozitron. Jsou prezentovány první výsledky pro reakci C-12+C-12 při energii 2 A GeV.
