Strangeness fluctuations and MEMO production at FAIR
arXiv:0811.4077 · doi:10.1016/j.physletb.2009.04.062
Abstract
We apply a coupled transport-hydrodynamics model to discuss the production of multi-strange meta-stable objects in Pb+Pb reactions at the FAIR facility. In addition to making predictions for yields of these particles we are able to calculate particle dependent rapidity and momentum distributions. We argue that the FAIR energy regime is the optimal place to search for multi-strange baryonic object (due to the high baryon density, favouring a distillation of strangeness). Additionally, we show results for strangeness and baryon density fluctuations. Using the UrQMD model we calculate the strangeness seperation in phase space which might lead to an enhanced production of MEMOs compared to models that assume global thermalization.
