Abstract: Charm penguin diagrams are known to be the main contribution

to decay process with strangeness variation equal to minus one which

is the case of B +—> K − K + K +decay. The wide phase space

available allows non trivial final state interactions. In this work

we investigate the hypothesis of charm Penguin duality contribution

to B + —> K − K + K + , described by a hadronic triangle loop in the

nonperturbative regions of the phase space, and by a partonic loop at

the quasi perturbative region. These nonresonant amplitudes must have

a particular signature that should be seen in data analyses.
