Flavor changing neutral current decays of B meson mediated via
b → s l+ l-
transition process. In this concept, we represents a lepton pairs provide promising detect for physics beyond the standard model.

We will study the charmless B+ → P anti-Λ l+ l- process using a
605 fb-1 data sample collected at the Υ(4S) resonance with the Belle detector at the KEKB collider.

There are significant signals found with the mass peaking near threshold and study the branching ratio various asymmetries of
B+ → P anti-Λ l+ l- four body baryonic decays of B meson.
