Abstract The purpose of the present project is to study the properties of some hadronic states whose structure seems to be more complex than that of three quarks for a baryon or-a quark-anti quark for a meson and where three hadron components, like, for example, two-meson and one baryon, three mesons, etc, seems to play a crucial role in the understanding of their properties. Investigations of three-hadron systems made of mesons and baryons is relatively novel subject which has attracted a lot of attention in recent times. These studies nave shown that several excited baryons and mesons can be generated in, and hence classified as, three-body resonances which consequently has contributed in reproducing and interpreting some of the recent experimental data. Current interest in three-hadron systems, our successful studies and hints of existence of several resonances possessing large branching ratio to three hadrons encourages us to continue exploring such systems. The formalism will involve using unitary chiral dynamics to determine the interaction between the different hadrons and the solving the Faddeev equations in coupled channel approach to determine the amplitudes for the three-body systems.
