Once again about the reaction phi(1020)-> gamma-pi-pi
Abstract
Gauge invariance constraints and analytical properties of the amplitudes e+ e- -> gamma-pi-pi and phi(1020) -> gamma-pi-pi are discussed in line with the criticism of N.N. Achasov in hep-ph/0606003. I show that the formulae of our paper (Yad. Fiz. 68 1614 (2005) [PAN 68 1554 (2005)], hep-ph/0403123) have nothing common with those N.N. Achasov claims to be ours - his criticism is therefore misplaced.
