Reactions gamma gamma -> pi pi and gamma gamma -> K \bar K: the (IJ^{PC}=00^{++})-wave spectra at E_{gamma gamma}^{(c.m.)} = 300- 1900 MeV

A. V. Anisovich, V. V. Anisovich

We calculate the $00^{++}$-wave two-meson spectra for the reactions $\gamma \gamma \to {\pi }^0{\pi }^0$, $\gamma \gamma \to {\pi }^{+}{\pi }^{-}$, $\gamma \gamma \to K^0{\bar{K}}^0$ and $\gamma \gamma \to K^{+}{K}^{-}$ on the basis of: (i) the results of the $K…
