ca96d60a 6 AliAnalysisTaskLambdaOverK0sJets class
667b678a 7
ca96d60a 8 This program obtains the production of K0s and Lambdas and calculates
9 the correlation (in the variables phi and eta) with respect to the
10 triggers particles (high-pt charged particles).
11 It works with MC information and AOD tree.
