We suggest a simple analytical description of the S-wave isoscalar $\pi\pi$ amplitude, which corresponds to a joint dressing of the bare resonance and background contributions. The amplitude describes well the experimental data on the $\delta^0_0$ ph

We analyze the existing data on the angular distributions of the $\gamma\gamma\to \pi^+ \pi^- ,\pi^0 \pi^0$ reactions with using of the unitary model for helicity 2 amplitude. The purpose is to obtain the D--wave parameters and S--wave cross section.

We carry out the semi--model analysis of existing data on the angular distributions of the $\gamma\gamma\rightarrow\pi^+ \pi^- ,\ \pi^0 \pi^0$ reactions with purpose to obtain S-wave cross section and D-wave's parameters. In the first time we obtain

We analyze the CELLO angular distributions $\gamma\gamma\rightarrow\pi^+\pi^-$ with the unitary model \cite{KS-86} for helicity 2 amplitude. In contrast to previous analysis \cite{CELLO} we do not see any QED damping. The obtained S--wave does not co
