The search for multi-quark states beyond the constituent quark model (CQM) has resulted in the discovery of many new exotic states, starting with the X(3872) discovery by Belle in 2003. Also in the sector of charm the CQM does not seem to describe properly all spectrum, despite of the theoretical expectations. These new forms of quark bounds clearly show that mesons and baryons are not the...

Five decades of work on the light scalar-meson nonet composed of $f_0(500)$, $f_0(980)$, $K_0^\star(800)$, and $a_0(980)$, as well as on other scalar mesons, will be briefly reviewed. The different phenomenological descriptions include tetraquark bound states, pure meson-meson models, unitarised effective chiral approaches, unitarised quark models, and lattice-QCD simulations. Also, the...

exotic charmonium-like states. In these talk, recent results of the measurements of
line-shape of e+ e- -> pi0 pi0 psi(3686), K K J/psi, and pi+ D0 D*-, as well as the
J^P determination of Zc(3900) and observation of e+ e- -> phi chi_c1/2 at
sqrt(s)=4.6 GeV will be presented.
