Abstract
For excited nucleon states of arbitrary spin coupling to nucleon (N) and meson we propose a Lorentz covariant orbital-spin scheme for the effective couplings. To be used for the partial wave analysis of various production and decay processes, it combines merits of two conventional schemes, i.e., covariant effective Lagrangian approach and multipole analysis with amplitudes expanded according to angular momentum L. As examples, explicit formulas are given for and processes which are under current experimental studies.
