Can I read Manifestations of the $a^0 0(980)-f 0(980)$ mixing in $D^0\to K^0 S\pi^+\pi^-$ and $D^0\to K^0 S\eta\pi^0$ decays on EtoBox?

Manifestations of the $a^0 0(980)-f 0(980)$ mixing in $D^0\to K^0 S\pi^+\pi^-$ and $D^0\to K^0 S\eta\pi^0$ decays by Achasov, N. N.; Shestakov, G. N. is a scholarly article available to read on EtoBox.

What is Manifestations of the $a^0 0(980)-f 0(980)$ mixing in $D^0\to K^0 S\pi^+\pi^-$ and $D^0\to K^0 S\eta\pi^0$ decays about?

Possible manifestations of the isospin-breaking mixing of the $a^0_0(980)$ and $f_0(980)$ resonances are analyzed in the $D^0\to K^0_S \pi^+\pi^-$ and $D^0\to K^0_S\eta\pi^0$ decays. It is shown that the $a^0_0(980)-f_0(980)$ mixing has the most influence on the $\pi^+\pi^-$ mass spectrum in the decay $D^0\to K^0_S\pi^+\pi^-$. Owing to the $a^0_0(980)-f_0(980)$ mixing, the $f_0(980)$ peak in $D^0 \to K^0_Sf_0(980)\to K^0_S \pi^+\pi^-$ can experience distortions comparable with its size. The effect essentially depends on the relative phase between the amplitudes of the $D^0\to K^0_Sf_0(980)$ and $D^0\to K^0_Sa^0_0(980)$ transitions.
