    "abstract": "The role of dynamics in spin observables for pseudoscalar meson\nphotoproduction is investigated using a density matrix approach in a multipole\ntruncated framework. Extraction of novel rules for $\\gamma p \\rightarrow \\pi^+\nn,~ K^+ \\Lambda$ and $\\eta p$ reactions based on resonance dominance, and on\nother broad and reasonable dynamical assumptions, are discussed. Observables\nthat are particularly sensitive to missing nucleonic resonances predicted by\nquark-based approaches, are singled out.",
