“…where the value of BR(p#(3S1) ---, K*/{,/(*K) measured in [9] was increased by 30% to account for unobserved channels. In the absence of experimental data for the BR(p#(3S1) ~ p+p-(I = 1)) the value in (44) has been taken from the theoretical model [10] which overall well describes the measured two-meson branching ratios.…”

Abstract. The leading two meson doorway contributions to the reaction tip ~ r due to K*/( and pp intermediate states are calculated beyond unitarity approximation. The dependence of the results on the off-shell parametrization is explored and the effect of the finite width of the propagating mesons is estimated. The rates obtained from the rescattering mechanisms are in agreement with the data for ;0p ~ r annihilation at rest. The vertices entering the calculation do not require any unexplained OZI violation, in particular no substantial sg configuration in the nucleon appears to be needed.

“…In both cases the on-shell approximation has been evaluated, in addition the effect of vertex functions for the kaon exchanged in the crossed channel has been evaluated in [8]. Using experimental information [10] on the lower limit for the branching ratio of the subprocess Bpp_.K.~=23.4x10 -4 the branching ratio for q~ ~o in on-shell approximation is B(pp--*K*ff~--*4)7c~…”

Abstract. The OZI suppressed reactions Dp--,q~b and ~p-, ~rq~ are reanalyzed, evaluating the unitarity contributions from two meson intermediate states with full spin, partially correcting earlier results. An estimate for ~p -, ~rg~b without spin is also given. Together with earlier VDM results for ,~p--* d?? the conservative estimates reported here easily explain the observed rates for all the q5 meson channels considered. PACS" 13.75Cs; 12.40Vv
