    "abstract": "Our main observations are: (i) The effective path length of the $c\\bar c$\nwave packet, which is produced in the nucleus, grows with the energy of the\nproduced charmonium. The variation is controlled by the coherence length\n$l_c=2E_{\\Psi}/M^2_{\\Psi}$. (ii) A colorless $c\\bar c$ wave packet produced in\n$pp$-interaction is a specific linear combination of the $J/\\Psi$ and $\\Psi\u0027$\nstates, and interacts substantially weaker that any of its components. The time\nevolution of this wave packet is controlled by the formation length,\n$l_f=2E_{\\Psi}/(M^2_{\\Psi\u0027} - M^2_{\\Psi})$. Exact formulas incorporating with\nthese effects are derived. The interplay of the two phenomena results in a\nnontrivial energy- and $x_F$-dependence of the nuclear suppression of the\ncharmonium production in proton-nucleus and nucleus-nucleus collisions and\nexplains some of the experimentally observed effects.",
