Abstract
Recent Serpukhov measurements of meson-baryon total cross sections allow comparisons with the Johnson-Treiman and Barger-Rubin relations. For 25-55-GeV/c incident meson momenta, the Johnson-Treiman relation, $\frac{1}{2}\ensuremath{\Delta}(\mathrm{Kp})=\ensuremath{\Delta}(\ensuremath{\pi}p)$, is well satisfied. The less restrictive Barger-Rubin relation holds for most of the Serpukhov points. Linear extrapolation of Serpukhov fits for $\ensuremath{\Delta}(\mathrm{Kp})$ and $\ensuremath{\Delta}(\ensuremath{\pi}p)$ to high momenta leads to the prediction of large violations of the Johnson-Treiman relations.
