Description
Inspired by the Faddeev-Merkuriev approach [1] we have modified the four-body Faddeev-Yakubovsky [2] equations, writing them in a form suitable to solve the four-body Coulomb problem. The newly developed formalism has been applied to study bound and some resonant states in (Ps)$_2$ and $\overline{H}$-Ps compounds. The first successful attempt to describe low energy Ps-Ps and $\overline{H}$-Ps scattering has been also realized. The aforementioned systems represent great interest for the experiments with antimatter (like AEGIS, ALPHA or GBAR) carried out at CERN .
