| Abstract: | We raise for the first time the highly important question that the hadronization of partons one by one as assumed in current models for crossover in QCD, contradicts color confinement. A possible mechanism — molecule-like hadron aggregation — is proposed for crossover compatible with color confinement. A toy model to realize this mechanism is constructed. A kind of grape-shape quark gluon plasma (gQGP) is obtained. Pair distribution function for gQGP is calculated which exhibits the character of liquid. |
