    "abstract": "MAID is a unitary isobar model for a partial wave analysis of pion photo- and\nelectroproduction in the resonance region. It is fitted to the world data and\ncan give predictions for multipoles, amplitudes, cross sections and\npolarization observables in the energy range from pion threshold up to W=2 GeV\nand photon virtualities Q^2 \u003c 5 GeV^2. Using more recent experimental results\nfrom Mainz, Bates, Bonn and JLab for Q^2 up to 4.0 GeV^2, the Q^2 dependence of\nthe helicity couplings A_{1/2}, A_{3/2}, S_{1/2} has been extracted for a\nseries of four star resonances. We compare single-Q^2 analyses with a\nsuperglobal fit in a new parametrization of Maid2005. Besides the (pion) MAID,\nat Mainz we maintain a collection of online programs for partial wave analysis\nof eta, eta\u0027 and kaon photo- and electroproduction which are all based on\nsimilar footings with field theoretical background and baryon excitations in\nBreit-Wigner form.",
