Phys. Rev. Lett. 88, 062301 (2002) [4 pages]Λ Spectra in 11.6A GeV/c Au-Au CollisionsReceived 8 May 2001; published 25 January 2002 E896 has measured Λ production in 11.6AGeV/c Au-Au collisions over virtually the whole rapidity phase space. The midrapidity pt distributions have been measured for the first time at this energy and appear to indicate that the Λ hyperons have 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 mt spectra at midrapidity. The data, where overlap occurs, are consistent with previously reported measurements. © 2002 The American Physical Society URL:
