Amplitude analysis of the $\overline{N}N\to K^{-}{K}^{+}$ reaction

Abstract

A simple partial wave amplitude analysis of $\overline{p}p\to K^{-}{K}^{+}$ has been performed for data in the range $p_{\mathrm{lab}}$ = 360 -- 1000 MeV/$c$. In this low momentum interval only partial wave amplitudes with $J$ equal to 0, 1 and 2 are needed to obtain a good fit to the experimental data. This maximal $J$ = 2 value is smaller than what is required for the data of the reaction $\overline{p}p\to {\pi }^{-}{\pi }^{+}$ in the same momentum interval.
