Description
We discuss a novel formulation of the quark confinement potential in the quark model viewpoint. The new formula contains the multi-body string-like potential, that allows hidden-color configurations besides two-meson states. We apply this formulation to the newly discovered $cc\bar c\bar c$ tetraquark states and find an interesting spectrum for the system. We suggest some bound states as well as resonances in the S-wave $cc\bar c\bar c$.
