Hadron ID and event-by-event fluctuations of the kaon to pion ratio in the CBM experiment — •Dmytro Kresan, Claudia Hoehne, and Volker Friese for the CBM collaboration — Gesellschaft fuer Schwerionenforschung, Darmstadt, Deutschland

Event-by-event fluctuations of the kaon to pion ratio are considered as a signature for the Critical Point of the QCD Phase Diagramm and are one of the key observables of the future CBM experiment at FAIR. We present results of simulation of the CBM detector to perform measurements of the event-by-event fluctuations of the kaon to pion ratio for central gold on gold collisions at 25 AGeV from UrQMD. Full event reconstruction and hadron ID are considered. Using a Generic Model, we show the dependence of dynamical fluctuations on the resonance yield for K* and phi mesons. With the signal from the Generic Model we show the sensitivity to different values of dynamical fluctuations. Supported by EU-FP6 Hadron Physics.
