Evaluation of the polarization observables I S and I C in the reaction γp → π 0 ηp

. We evaluate the polarization observables I S and I C for the reaction γp → π 0 ηp , using a chiral unitary framework developed earlier. The I S and I C observables have been recently measured for the ﬁrst time by the CBELSA/TAPS collaboration. The theoretical predictions of I S and I C , given for altogether 18 angle dependent functions, are in good agreement with the measurements. Also, the asymmetry dΣ/d cos θ evaluated here agrees with the data. We show the importance of the ∆ (1700) D 33 resonance and its S -wave decay into η∆ (1232). The result can be considered as a further conﬁrmation of the dynamical nature of this resonance. At the highest energies, deviations of the predictions from the data start to become noticeable, which leaves room for additional processes and resonances such as a ∆ (1940) D 33 . We also point out how to further improve the calculation.
