Total Cross Sections ofK±Mesons and Antiprotons on Nucleons up to 3.3 GeV/c

Abstract

Total cross sections of ${K}^{\ifmmode\pm\else\textpm\fi{}}$ and $\overline{p}$ on hydrogen and deuterium were measured in a standard transmission experiment with statistical precisions of the order of 0.05-0.25%. Data were obtained in the momentum range 2.45-3.30 GeV/c for ${K}^{\ensuremath{-}}N$, 1.55-3.30 GeV/c for ${K}^{+}N$, and 1.00-3.30 GeV/c for $\overline{p}N$. Cross sections for the pure isotopic spin states are obtained using a procedure for the deuterium data which takes into account Fermi motion and the shadow effect. Evidence for the following new structures was found: ${{Y}_{1}}^{*}(2455)$, ${{Y}_{1}}^{*}(2620)$, ${{Y}_{0}}^{*}(2585)$, ${{Z}_{1}}^{*}(2150)$, ${{Z}_{1}}^{*}(2500)$, ${{\ensuremath{\pi}}_{1}}^{*}(2290)$, ${{\ensuremath{\pi}}_{1}}^{*}(2350)$, and ${{\ensuremath{\pi}}_{0}}^{*}(2375)$.
