Abstract:

This analysis is focused on the first measurement of net-Lambda fluctuations at STAR. Net-Lambda fluctuations may provide important information about the chemical freeze-out during the hadronization process in the context of both strangeness and baryon number fluctuations. For more details please see the previous presentations at the links bellow:
