Abstract
We explain the observed double-pole characteristics of the by a nondiagonalizable degenerate mass matrix for two mesons one of which decays predominantly into . The presence of the other, possibly already observed meson would cause the characteristics to change considerably from one production process to another. From available limited statistics experiments (except for the CERN work discussed here), this appears likely.
