Description

Two-particle azimuthal correlations are an ideal tool to study high $p_{\rm T}$ parton fragmentation without full jet reconstruction. Enhancements of the azimuthal correlations are seen at $\Delta \varphi = 0$ and $\Delta \varphi = \pi$, corresponding to the near-side and away-side jets, respectively. We present correlations between charged leading particle and associated strange baryons ($\Lambda$) and mesons (${\rm K_s^0}$) in pp collisions at $\sqrt{s}$ = 7 TeV. Associated particle yields in near- and away-side jets, as well as in the underlying event, were extracted in different $p_{\rm T}$ intervals from 1 GeV/$c$ to 6 GeV/$c$. Extracted $\Lambda/{\rm K_s^0}$ in jets and the underlying event were compared to the inclusive $\Lambda/{\rm K_s^0}$ ratio and pQCD-inspired models.
