Abstract In this paper the theoretical parameters of theZ line shape, such asM Z andΓ Z, and the one photon exchange diagram are related to a set of parameters characterizing the experimental line shape. The latter are the peak height σmax, peak position $$\sqrt {s_{\max } } $$ and half peak positions $$\sqrt {s_ \pm } $$ . The rules of thumb are accurate within 10 MeV. As a result we obtain approximate formulae which expressM Z and ΓZ in the measured $$\sqrt {s_{\max } } $$ and $$\sqrt {s_ + } - \sqrt {s_ - } $$ .
