Abstract (data abstract)

CERN-LHC. Measurement of the $\bar{\Lambda}/\Lambda$ and $\bar{\Lambda}/K^{0}_{s}$ ratios in proton-proton collisions at centre-of-mass energies of 0.9 TeV and 7 TeV. The analysis is based on data having a total integrated luminosity of 0.3 nb$^{-1}$ at 0.9 TeV and 1.8 nb$^{-1}$ and 7 TeV and covers the transverse momentum range 0.15-2.50 GeV$/c$ and rapidity 2.0-4.5. Data at both energies are compared as a function of rapidity loss (with respect to the corresponding beam rapidity), showing good agreement.
