The B->Kpipi modes have awaken recently interest because the three body final state can be reach through a variety of resonant intermediate modes (i.e. B->rho K and K*pi), allowing to access a great variety of observables. The B->Kpipi modes then offers a reach phenomenology. In this seminar I will describe the experimental techniques to measure such modes and the phenomenological framework to interpret them. I will present the current status and as well as prospectives of the reach of the method for the future LHCb and Belle-II data.
The seminar will take place in the réunion de vendredi.
