ππ−KK¯Model of theρMeson

The parameters of the $\rho$ meson are calculated in the coupled $\pi \pi -K\overline{K}$ problem, using a simple version of the strip approximation. Experimental values are taken for the $\pi$, $K$, $K^{*}$, and $\phi$ masses, while all the coupling constants are assumed to be related through $\mathrm{SU}\left(3\right)\mathrm{}$. The width of the $\rho$ turns out to be 360 MeV, while the mass is 765 MeV. Possible corrections to the model are discussed.
