J. Bachler et al., STUDY OF PARTICLE SPECTRA WITH AN OPTICALLY READOUT RICH DETECTOR IN THE NA35 EXPERIMENT, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 343(1), 1994, pp. 288-291
The first identified particle spectra obtained with a proximity focusi
ng RICH detector using an optical readout in the high particle density
environment of heavy ion collisions at ultrarelativistic energies are
presented. The rapidity and transverse momentum spectra of identified
pions, kaons, and protons measured in the reaction S-Au at 200 GeV/nu
cleon are shown and compared with the predictions of two event generat
ors (Fritiof and VENUS).
