Can I read Pion Scalar Form Factor and Model Independent Values of $F 0(500)$ and $F 0(980)$ Meson Parameters on EtoBox?

Pion Scalar Form Factor and Model Independent Values of $F 0(500)$ and $F 0(980)$ Meson Parameters by Dubnicka, S.; Dubnickova, A. Z.; Liptaj, A. is a scholarly article available to read on EtoBox.

What is Pion Scalar Form Factor and Model Independent Values of $F 0(500)$ and $F 0(980)$ Meson Parameters about?

The pion scalar form factor along with all existing S-wave iso-scalar $\pi\pi$-scattering phase shift data in the elastic region up to $1 {\rm GeV}^2$ are applied for a determination of the $f_0(500)$ and $f_0(980)$ meson parameters $m_{f_0(500)}=(360\pm33){\rm MeV}$, $\Gamma_{f_0(500)}=(587\pm 85){\rm MeV}$ and $m_{f_0(980)}=(957\pm77) {\rm MeV}$, $\Gamma_{f_0(980)}=(164\pm142){\rm MeV}$ in a model independent way.
