Abstract QCD predictions for moments of multiplicity distributions are compared with experimental data on e+e− collisions and their two-NBD fits. Moments of the multiplicity distribution in a two-NBD model for 1.8 TeV pp-collisions are considered. Three-NBD model predictions and fits for pp at LHC energies are also discussed. Analytic expressions for moments of hybrid NBD are derived and used t...

An exactly solvable model of nuclear fragmentation is shown to lead to a simple connection between the critical point multiplicity m c and the critical point exponent τ recently reported on in the EOS collaboration. The importance of multiplicity fluctuations on critical point behavior is also discussed.

The Potential Energy Surface PES of (H2)2 dimer has been investigated, using five simple rigid rotor models. These models are called: head to head, symmetric side to side, L , steplike and T model. All calculations were done at two levels of ab initio  methods: MP2(Full) and QCISD (T,Full) using cc-pVTZ basis set at singlet state of spin multiplicity. The results of scanning PES were then fitte...
