Strange particle production in proton-proton collisions at $\sqrt{s}=0.9$ TeV with ALICE at the LHC

ALICE Collaboration

The production of mesons containing strange quarks (K${}_s^0$, $\varphi$) and both singly and doubly strange baryons ($\Lambda$, Anti-$\Lambda$, and $\Xi$+Anti-$\Xi$) are measured at central rapidity in p…
