Institut für Theoretische Physik, Universität Regensburg, Postfach 397, D-8400, Regensburg, Germany aut Diquarks from a U (3) L × U (3) R invariant quark Lagrangian [Elektronische Daten] [U. Vogl] An effective Lagrangian involving composite pseudoscalar and scalar mesons as well as scalar and pseudoscalardiquarks is derived from a chiralU(3) L ×U(3) R invariant four-quark theory using path integral methods. We obtain mass relations for the diquarks where all free parameters can be fixed in the meson sector. We also calculate weak diquark decay constants, and discuss baryon masses in terms of a quark-diquark model.
