Resumen:
The production of Kshort and Lambda hadrons is studied in inelastic pp
collisions at sqrt(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 Lambdabar to Lambda
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 Kshort distributions, substantial disagreements
with data are found in the Lambda distributions of transverse momentum.
