Sa-wave γγ→ππ and f0 (980)→ππ
We report on a dispersion relation for the γγ→(ππ)I Sa-wave in isospin I emphasizing the low energy region. The f0(980) signal that emerges in γγ→ππ is also discussed. Our results could be used to distinguish between different ππ isoscalar Sa-wave parameterizations. We also calculate the width of th...
