In the two-quark model supposition for K0ββ(1430), the branching ratios
and the direct CP-violating asymmetries for decays BΛs0ββK0β0β(1430)Ο0,K0β+β(1430)Οβ are studied by employing the
perturbative QCD factorization approach. We find that although these two decays
are both tree-dominated, the ratio of their penguin to tree contributions are
very different: there is only a few percent for the decay BΛs0ββK0β+β(1430)Οβ, while about 37% in scenario I, even 51% in scenario II
for the decay BΛs0ββK0β0β(1430)Ο0. It results that these two
decays have very different values in the branching ratios and the direct CP
asymmetries. The branching ratio of the decay BΛs0ββK0β+β(1430)Οβ is at the order of 10β5, and its direct CP asymmetry
is about (20-30)%. While for the decay BΛs0ββK0β0β(1430)Ο0, its
direct CP-violating asymmetry is very large and about 90%, but it is difficult
to measure it, because the branching ratio for this channel is small and only
10β7 order.Comment: 8pages, 2figure
