Query: String percolation in AA and p+p collisions   A brief review of the string percolation model and its results are presented
together with the comparison to experimental data. First, it is done an
introduction to the quark-gluon phase diagram and the lattice results
concerning the confinement and the percolation of center domains. It is studied
the interaction of the strings produced in nucleus-nucleus and proton-proton
collisions showing how the string percolation arises. The main consequences of
the string percolation, concerning the dependence on the energy and centrality,
on the multiplicities and the mean transverse momentum are obtained comparing
with experimental data. It is emphasized the non-abelian character of the color
field of the strings forming the cluster to reproduce the rise of the
transverse momentum with multiplicity and the relative suppression of
multiplicities. It is also studied different observables like multiplicity and
transverse momentum distributions, dependence with multiplicity and transverse
momentum correlations, forward-backward correlations, the strength of the
Bose-Einstein correlations, dependence on the multiplicity of $J/\Psi$
production and its possible suppression in pp collisions at high multiplicity,
strangeness enhancement, elliptic flow, and ridge structure. The comparison
with the data shows an overall agreement. The thermodynamical properties of the
extended cluster formed in the collision are discussed computing its energy and
entropy density, shear viscosity over entropy density ratio, bulk viscosity,
sound speed and trace anomaly as a function of temperature, showing a
remarkable agreement with lattice QCD evaluations. The string percolation can
be regarded as the initial frame able to describe the collective behavior
produced in AA and pp collisions.
