[en] The method of jet construction by event decomposition is tested and compared to the jet construction method by cone forming. Its potential for recovering parton kinematics from large p_t and from photon remnant jets is investigated in detail. Effects from the response of a realistic detector (H1) are included. The hard scattering parton kinematics can be reconstructed with comparable quality as in the cone method. The reconstruction of the photon remnant jet mass by event decomposition provides clear advantages in comparison with the cone method for separating direct and resolved photon reactions. (orig.)
