K0s and Λ production in pp interactions at s√=0.9 and 7 TeV measured with the ATLAS detector at the LHC Aad, G. Aguilar Saavedra, Juan Antonio Atlas Collaboration LHC (Large Hadron Collider) Atlas detector The production of K0S 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 within well-defined phase-space regions. The distribution of the production ratio of Λ¯¯ to Λ baryons is also measured. The results are compared with various Monte Carlo simulation models. Although most of these models agree with data to within 15% in the K0S distributions, substantial disagreements are found in the Λ distributions of transverse momentum. 2014-02-25T09:50:19Z 2014-02-25T09:50:19Z 2012 info:eu-repo/semantics/article Aad, G.; et al.
