ABSTRACT
Detailed study of centrality dependence low-p_t manifestation so-called "near-side ridge" phenomenon is reported recently by STAR for all charged hadrons with p_t>0.15 GeV/c from AuAu collisions at 62 and 200 GeV RHIC[1]. It indicating the existence energy-dependent point where some sudden changes in correlation pattern are observed. In present work we use hypothesis string percolation phase transition description onset this ridge. One may assume that formation rather large "macroscopic" clusters composed several overlapped strings extended rapidity localized azimuth could be one possible processes leading to observed phenomenon. This characterized definite ("critical") number participating nucleons. We also another physical quantity, transverse particle density, characterize threshold behavior, variable brings points two energies coincidence [1]. So parameters model defined these critical points. Also results our previous calculations[2] energy collision 17.3 based on anomalous suppression J/psi. Obtained extrapolated AA pp over range - 7000 GeV.
