We report a partial-wave analysis of new data on the double-polarizationvariable $E$ for the reactions $\gamma p\to \pi^+ n$ and $\gamma p\to \pi^0 p$and of further data published earlier. The analysis within the Bonn-Gatchina(BnGa) formalism reveals evidence for a poorly known baryon resonance, theone-star $\Delta(2200)7/2^-$. This is the lowest-mass $\Delta^*$ resonance withspin-parity $J^P=7/2^-$. Its mass is significantly higher than the mass of itsparity partner $\Delta(1950)7/2^+$ which is the lowest-mass $\Delta^*$resonance with spin-parity $J^P=7/2^+$. It has been suggested that chiralsymmetry might be restored in the high-mass region of hadron excitations, andthat these two resonances should be degenerate in mass. Our findings are inconflict with this prediction.

Evidence for $\Delta(2200)7/2^-$ from photoproduction and consequence for chiral-symmetry restoration at high mass
