Search for Structures inp¯pTotal Cross Section below 1 GeV/c

Abstract

A search has been made for resonant structures with a width greater than 10 MeV/${\mathit{c}}^2$ in $\overline{p}p$ total cross section between 335 and 960 MeV/c. The measurement has been performed by a transmission method supplemented with proportional chambers and a beammonitoring spectrometer. No resonant structure has been found, and 90% confidence-level upper limits for the resonant cross sections are presented.
