Beta decay transitions between mirror nuclei, so-caled "mirror transitions", offer a sensitive window to study the structure and symmetries of the weak interaction. Data from mirror transitions have enabled the determination of standard model parameters, such as Vud element of the quark mixing matrix and provide also a mean to search for physics beyond the standard model. The sensitivity of mirror transitions is possibly best recognized in the decay of the free neutron but has otherwise not received particular attention in heavier nuclei. In this presentaion I will discuss the role of correlation measurements in mirror transitions for both, the determination of standard model parameters and tyhe search for new physics. The emphasis will be given on correlation measurements involving spin observables that require polarized low energy beams.
