Theoretical analysis of the $\gamma \gamma \to {\pi }^0\eta$ process

Igor Danilkin, Oleksandra Deineka, Marc Vanderhaeghen

We present a theoretical study of the $\gamma \gamma \to \pi \eta$ process from the threshold up to 1.4 GeV in the $\pi \eta$ invariant mass. For the s-wave $a_0(980)$ resonance state we adopt a dispersiv…
