  In these proceedings, measurements of angular correlations between hadron
pairs in pp collisions obtained by the ALICE experiment at the LHC are
presented and compared with phenomenological predictions. Correlations between
particles carrying the same and opposite quantum numbers are studied to
understand the hadron production mechanism, and the difference between
same-sign and opposite-sign correlations is used to probe charge-dependent
effects in particle production. Correlation measurements dominated by minijet
fragmentation agree well with the models, but other results, in particular
correlations between baryons and strange hadrons, are not yet understood.
