Beam-recoil transferred polarizations for the exclusive electroproduction of$K^+\Lambda$ and $K^+\Sigma^0$ final states from an unpolarized proton targethave been measured using the CLAS12 spectrometer at Jefferson Laboratory. Themeasurements at beam energies of 6.535~GeV and 7.546~GeV span the range offour-momentum transfer $Q^2$ from 0.3 to 4.5~GeV$^2$ and invariant energy $W$from 1.6 to 2.4~GeV, while covering the full center-of-mass angular range ofthe $K^+$. These new data extend the existing hyperon polarization data fromCLAS in a similar kinematic range but from a significantly larger dataset. Theyrepresent an important addition to the world data, allowing for betterexploration of the reaction mechanism in strangeness production processes, forfurther understanding of the spectrum and structure of excited nucleon states,and for improved insight into the strong interaction in the regime ofnon-perturbative dynamics.
