K0s measurements at ATLAS with the first LHC data — •Thorsten Voß, Grant Gorfine, Thorsten Kuhl, Peter Mättig, and Marcello Barisonzi — Bergische Universität, Wuppertal, Deutschland

This talk will present an analysis, based on the K0s decay into two charged pions. The first part will summarize the K0 reconstruction mechanism, validated and tuned on simulated events. In the second part of the talk results on the K0s, measured at ATLAS in the first LHC data, are shown and compared with monte carlo predictions. In addition mechanisms to understand the detector performance using K0 properties are presented.
