    "abstract": "If nuclear collisions lead to QGP formation then the ratio of $\\psi\\prime$\nover $J/\\psi$ will remain constant with $E_T$ as both $J/\\psi$ and $\\psi\\prime$\nare melted in the QGP. On the other hand, if hot hadronic matter is produced,\nthe ratio will continually fall with $E_T$, as $\\psi\\prime$\u0027s are more\nsuppressed in hadronic matter than the $J/\\psi$\u0027s. From the existing NA50 Pb+Pb\ndata, we have constructed the ratio $\\sigma(\\psi\\prime)/\\sigma(J/\\psi)$, as a\nfunction of $E_T$. The ratio give indication of QGP formation, but definite\nconclusion can not be reached. We have also given the prediction for the ratio\nat RHIC energy. If QGP is formed at RHIC, it could be detected from the ratio.",
