Mesons of the $f_0$ family in processes $\pi \pi \to \pi \pi ,K\bar{K}$ up to 2 GeV and chiral symmetry

Yu. S. Surovtsev, D. Krupa, M. Nagy

In a combined analysis of the experimental data on the coupled processes $\pi \pi \to \pi \pi ,K\bar{K}$ in the channel with $I^G{J}^{PC}=0^{+}{0}^{++}$, the various scenarios of these reactions (wit…
