Particules inconnues II

The X and Y particles predicted in part I have presumably masses of about 2150 and 2900 e. m. respectively. They may decay respectively into a nucleon and a Xi-hyperon by emitting a pion; lifetimes of the order of 10-10 s may be expected (weak interactions). The mass of the D-meson is about 1670 e. m. and it decays into a K-meson and one or two pions. Leptonic modes of decay are also possible. The dimension 3 of the charge-space introduced ina preceding paper is confirmed. The correlations considered in tha paper are re-examined.
