Abstract: An impact parameter and secondary-vertex based charm tagging algorithm, JetFitterCharm,has been developed to distinguishc-quark jets from eitherb-quark or light-flavoured (u,d,s-quark or gluon) jets. JetFitterCharm is the first such algorithm used in ATLAS physicssearches. This note presents both the expected performance in simulation and results fromcalibrating the tagging eciencies ofb-quark,c-quark and light-flavoured jets with data.The calibrations are presented in the form of scale factors, corresponding to the ratios ofthe tagging eciencies measured in data to those in simulation. Both simulation and dataare based onps=8 TeVppcollisions
