The data for the mean squared transverse momentum P_t as function of transverse energy E_t of J/Psi and Psi' produced in Pb-Pb collisions at the CERN-SPS are analyzed and it is claimed that they contain information about the time structure of anomalo

The transverse momentum dependence of J/Psi suppression in relativistic heavy ion collisions is calculated from initial state gluon rescattering not only with nucleons but also with prompt gluons produced in nucleon-nucleon collisions in the early ph

The recently published data for $$ for $J/\psi$ production in Pb-Pb collisions at 158 A GeV are analyzed. For low values of transverse energy $E_t$, where normal suppression dominates, $ (E_t)$ scales with the path length of the gluons

The observed J/psi suppression in Pb+Pb collisions shows a drop at those large values of the transverse energy E_T which arise from fluctuations. The validity of existing models for J/psi suppression can be extended into this domain of E_T by introdu

In high energy nuclear collisions, the Glauber model is commonly used to evaluate $J/\psi$ suppression due to inelastic interaction with colorless bound nucleons. This requires an effective value for the $J/\psi$-nucleon absorption cross section whic

In high energy nuclear collisions, the conventional Glauber model is commonly used to evaluate the contribution to $J/\psi$ suppression originating from the inelastic interaction with colorless bound nucleons. This requires an effective value for the

An upper limit on $n-\bar n$ oscillations can be obtained from the stability of matter. This relation has been worked out theoretically and together with data yields $\tau_{n\bar n} > (1 - 2)\times 10^8 sec$. A recent publication claims a different r

Values for the cross sections $\sigma^{\Psi N}_{tot}$ and $\sigma^{\Psi' N}_{tot}$ are of crucial importance, once one wants to understand nuclear suppression of $J/\Psi$($\Psi'$) in a search for the quark gluon plasma. Quoted values are usually extr

Our main observations are: (i) The effective path length of the $c\bar c$ wave packet, which is produced in the nucleus, grows with the energy of the produced charmonium. The variation is controlled by the coherence length $l_c=2E_{\Psi}/M^2_{\Psi}$.

We calculate the nuclear suppression for $J/\Psi$ and $\Psi'$ production within a coupled channel approach in the subspace of the $J/\Psi$ and $\Psi'$ states. We are able to explain, why (i) the $J/\Psi$ and $\Psi'$ show the same suppression from $20
