A lower bound of 135 MeV for the width of the ξmeson is obtained from analyzing the pp and pbar-p interactions by use of Regge theory. The pp data exclude a narrow ξas the latter would lead to total pbar-p cross sections far exceeding the measured ones. The broad width explains why the ξmay not be seen in pbarp-p experiments.
