Ks0 and Λ production in pp interactions at √s=0.9 and 7 TeV measured with the ATLAS detector at the LHC

The production of KS0 and Λ hadrons is studied in pp collision data at √s=0.9 and 7 TeV collected with the ATLAS detector at the LHC using a minimum-bias trigger. The observed distributions of transverse momentum, rapidity, and multiplicity are corrected to hadron level in a model-independent way wi...
