Measurements of the top quark mass using the ATLAS detector at the LHC

The top quark mass is a fundamental parameter of the Standard Model (SM). Thus measuring its value with the highest possible precision is important. The latest top quark mass measurements performed on data collected with the ATLAS detector are presented. In particular, results on standard top mass m...

Sumario:The top quark mass is a fundamental parameter of the Standard Model (SM). Thus measuring its value with the highest possible precision is important. The latest top quark mass measurements performed on data collected with the ATLAS detector are presented. In particular, results on standard top mass measurements are presented for the fully hadronic and fully leptonic $t\bar t\ $ decay modes. Also top quark pole mass measurements from $t\bar t\ $ inclusive cross section and $t\bar t\ $ + 1 jet differential cross section are shown.
