Title Advances in the studies of the nucleon resonance spectrum in experiments with electromagnetic probes.
Abstract The studies of the nucleon resonance spectrum with the focus on the search for new baryon states for a long time remain the challenging topic in hadron physics. Full resonance spectrum plays a critical role in the evolution of ~ millisecond age Universe in the transition from the quark-gluon to the hadron gas phases. Recent LQCD evaluations of the N*-spectrum from the first QCD principles suggest existence as much new nucleon resonances as expected in the quark models employed SU(6)*O(3) symmetry. Discovery of several new nucleon resonances in the global analyses of exclusive meson photoproduction off protons data with decisive impact from the CLAS measurements of exclusive KY photoproduction will be presented. Combined studies of charged double pion photo- and electroproduction data from CLAS revealed strong evidence for another N'(1720)3/2+ new baryon state. The information on electroexcitation amplitudes of this state has become available for the first time offering the insight to t
