Measurement of charged pions in C-12+C-12 collisions at 1 A GeV and 2 A GeV with HADES
Original language description
We present the results of a study of charged-pion production in C-12 + C-12 collisions at incident beam energies of 1 A GeV and 2 A GeV using the HADES spectrometer at GSI. The main emphasis of the HADES program is on the dielectron signal from the earlyphase of the collision. Here, however, we discuss the data with respect to the emission of charged hadrons, specifically the production of pi(+/-) mesons, which are related to neutral pions representing a dominant contribution to the dielectron yield. We have performed the first large-angular-range measurement of the distribution of pi(+/-) mesons for the C-12 + C-12 collision system covering a fairly large rapidity interval. The pion yields, transverse-mass and angular distributions are compared withcalculations done within a transport model, as well as with existing data from other experiments. The anisotropy of pion production is systematically analyzed.
