  The strong interaction among hadrons has been measured in the past by
scattering experiments. Although this technique has been extremely successful
in providing information about the nucleon-nucleon and pion-nucleon
interactions, when unstable hadrons are considered the experiments become more
challenging. In the last few years, the analysis of correlations in the
momentum space for pairs of stable and unstable hadrons measured in pp and p-Pb
collisions by the ALICE Collaboration at the LHC has provided a new method to
investigate the strong interaction among hadrons. In this article, we review
the numerous results recently achieved for hyperon-nucleon, hyperon-hyperon,
and kaon-nucleon pairs, which show that this new method opens the possibility
of measuring the residual strong interaction of any hadron pair.
