We propose a simple model of production of strange baryons and antibaryons in nuclear collisions at the CERN SPS. The model takes into account both the increase of strangeness production in collisions of lighter ions and a possibility of…

We discuss the dependence of J/\psi\ production on the charged particle multiplicity in proton-proton collisions at LHC energies. We show that, in the framework of parton saturation or string interaction models, the hard J/\psi\ production…

The apparent production of (multi-)strange baryons and mesons at sub-threshold energies in proton-heavy ion collisions is a consequence of short range correlations (SRC), which have recently been observed in lepton-nucleus scattering. They…

We show that the dependence of the charged particle multiplicity on the centre-of-mass energy of the collision is, in the String Percolation Model, driven by the same power law behavior in both proton-proton and nucleus- nucleus collisions.…

The $p_T$ distributions of the $K^0$- and $\phi$ - mesons produced in the $pp$ collisions at $\sqrt{s}=2.76 TeV$ have been analyzed by fitting them using the exponential function. It was observed that the distributions contain several $p_T$…
