Lambda Production at Forward Rapidity in d+Au Collisions at sNN = 200 GeV — •Frank Simon — Max–Planck–Institut für Physik, München, Germany

We present results on the production of lambda and anti-lambda particles at forward rapidity in d+Au collisions at √sNN = 200 GeV. Using the forward time projection chambers in the STAR experiment, measurements of net lambda yields and the anti-lambda/lambda ratio at forward and backward rapidity at y = ± 2.75 were obtained.

The contributions of different processes to particle production and baryon transport are probed using the asymmetry of d+Au collisions. Comparisons to a variety of model calculations show that the baryon transport on the deuteron side is due to multiple collisions of the deuteron nucleons with gold participants, while on the gold side the inclusion of target excitations or hadronic transport appears to be necessary.
