Λ Spectra in 11.6 A GeV / c Au-Au Collisions

E896 has measured A production in 11.6A GeV/c Au-Au collisions over virtually the whole rapidity phase space. The midrapidity p t distributions have been measured for the first time at this energy and appear to indicate that the A hyperonshave different freeze-out conditions than protons. A comparison with the relativistic quantum molecular dynamics model shows that while there is good shape agreement at high rapidity the model predicts significantly different slopes of the m t spectra at midrapidity. The data, where overlap occurs, are consistent with previously reported measurements.
