Abstract

In a recent experiment at the CERN Proton Synchrotron (PS) the proton-antiproton excitation functions of the annihilation as well as of the elastic channel have been measured in the laboratory momentum range from 370 to 1000 MeV/c. The experiment was characterized by an r.m.s. mass resolution of 0.4 MeV/c2 and a statistical accuracy of 1.2% for the annihilation channel. With this precision a narrow structure, about 4 MeV/c2 wide, at a mass of 1936 MeV/c2 is observed in the annihilation channel.
