AB  - The beam-spin induced polarization of Λ and ―Λ hyperons produced in deep-inelastic scattering of longitudinally polarized positrons from unpolarized nucleons is being investigated by the HERMES experiment at a positron beam energy of 27.6 GeV. The spin-transfer coefficients D<sub>LX</sub> and D<sub>LZ</sub>, i.e., transverse and along the hyperon momentum direction, are studied as function of the relevant kinematic variables. A novel extraction method, which does not rely on accurate detector-response simulations, is employed and presented here for the first time exploiting the regular reversal of the beam helicity at the HERMES experiment.
