  Semi-inclusive deep inelastic Scattering (SIDIS) has been a very successful
tool to investigate the partonic structure of the nucleon over the last decade.
Compared to inclusive DIS, information about the quantum numbers of the struck
quark can be inferred from the identity, distribution and polarization of the
final state hadrons. Up to now, virtually all knowledge about the quark-gluon
structure of the nucleon from SIDIS has been gained from distributions of
independently observed scalar hadrons. However, given the amount of data
current and future experiments at JLab, RHIC, KEK and the EIC will collect, new
paradigms have to be explored to leverage the statistical power of the data.
Similar to other felds in nuclear and particle physics, it is natural to move
towards the exploration of more complex correlations in the observed fi nal
state. This contribution will discuss recent results and future prospects of
using di-hadron correlations and polarized hyperon probes to study QCD in
SIDIS, pp and e+e- annihilation. Both of these probes exploit additional
degrees of freedom in the final state, given by the relative momentum of the
di-hadron pair and the hyperon polarization, respectively. This contribution
will focus on recent results and opportunities opened by these probes to study
nucleon structure, hadronization and QCD in novel ways. The focus will be on
planned SIDIS measurements at CLAS12 at JLab and e+e- at Belle II.
