【 摘 要 】

In this contribution, we briey analyze the formalism of the unquenched quark model (UQM) and its application to the description of several observables of hadrons. In the UQM, the effects of qq sea pairs are introduced explicitly into the quark model through a QCDinspired3P0pair-creation mechanism. We present our description of avour asymmetry and strangeness in the proton when baryon-meson components are included. In the meson sector, the charmonium and bottomonium spectra with self-energy corrections due to the coupling to the meson-meson components.
