Taking advantage of both the low-emittance proton beam of the cooler synchrotron COSY and the high momentum precision of the COSY-11 detector system, the mass distribution of the η' meson was measured with a resolution of 0.33  MeV/c2 (FWHM), improving the experimental mass resolution by almost an order of magnitude with respect to previous results.

Preprint version. The figures in here have reduced size and, thus, reduced quality. The original proposal can be accessed at i ii Executive Summary The document at hand describes the physics case, the key experiments proposed and the technical solution for the project " WASA at COSY " , which concerns the transfer of the WASA pellet-target and detector(More)
