Evidence for Δ(2200)7/2− from photoproduction and consequence for chiral-symmetry restoration at high mass
We report a partial-wave analysis of new data on the double-polarization variable E for the reactions γp→π+n and γp→π0p and of further data published earlier. The analysis within the Bonn–Gatchina (BnGa) formalism reveals evidence for a poorly known baryon resonance, the one-star Δ(2200)7/2−. This i...
