“…If similar soft string dynamics drives pp, pA and AA collisions then most of the global observables with the exception of the baryon-antibaryon asymmetry can also be inferred from already existing data. The FNAL E-735 data [15] on hadronic spectra inpp at √ s = 200 GeV suggests values for the particle ratios that come very close to preliminary RHIC data (shown for comparison in parentheses). Thep/π = 0.07 (0.08).…”

We study the apparent discrepancy between the standard PQCD predictions for the meson and baryon ratios and multiplicities at moderate high pT > 2 GeV and recent experimental measurements in Au + Au collisions at √ s NN = 130 GeV at the Relativistic Heavy Ion Collider (RHIC). We show that the differences, most pronounced in central collisions, can be explained by a strong non-perturbative baryon Junction component, which dominates the currently accessible experimental pT window and the non-abelian energy loss of fast partons propagating through hot and dense medium. The recently introduced two component hybrid model, which combines a quenched jet PQCD calculation in the Gyulassy-Levai-Vitev (GLV) formalism and a phenomenological "soft" part, is further elaborated to take into account the full 3D expansion in the pre-hadronization phase and include particle flavor dependent "soft" inverse slopes as suggested by the baryon Junction picture. We show that such approach can resolve what seems to be a factor of ≃ 2 difference in the moderate high pT suppression of π 0 and h − as recently reported by the PHENIX collaboration. The observed quenching of the high pT particle spectra and the largep/π − and p/π + ratios as a function of pT are found to be consistent with a creation of a deconfined phase and non-abelian energy loss of fast partons in a plasma of initial gluon rapidity density dN g /dy ∼ 1000

“…Motivated by Bjorken's predictions, there were experimental searches for signatures of QGP formation in p + p andp + p collisions, including Tevatron experiments E735 (13) and Mini-MAX (14). No firm conclusions resulted from this program, in part due to the non-comprehensive nature of these experiments; for example, MiniMAX exclusively searched for disoriented chiral condensates (DCC).…”

The bulk motion of nuclear matter at the ultrahigh temperatures created in heavy ion collisions at the Relativistic Heavy Ion Collider and the Large Hadron Collider is well described in terms of nearly inviscid hydrodynamics, thereby establishing this system of quarks and gluons as the most perfect fluid in nature. A revolution in the field is under way, spearheaded by the discovery of similar collective, fluid-like phenomena in much smaller systems including p + p, p + A, d+Au, and 3 He+Au collisions. We review these exciting new observations and their profound implications for hydrodynamic descriptions of small and/or out-of-equilibrium systems.

“…Refs. [20][21][22][23][24] corroborated the formation of QGP (Quark Gluon Plasma) in p-p collisions, which is the basis for the practicability of hydrodynamics in such collisions. The measurements from CMS Collaboration at CERN-LHC have shown that [25], just like in nucleus-nucleus collisions, the ridge structures, the signal of collective motion, also appear in p-p collisions.…”

In p-p collisions, the produced charge particles consist of two leading particles and those frozen out from the hot and dense matter created in collisions. The two leading particles are respectively in the projectile and target fragmentation region, which, in this paper, are conventionally supposed to have Gaussian rapidity distributions. The hot and dense matter is assumed to expand according to the unified hydrodynamics, a hydro model which unifies the features of Landau and Hwa-Bjorken model, and freeze out into charged particles from a space-like hypersurface with a fixed proper time of FO  . The rapidity distribution of this part of charged particles can be derived out analytically. The combined contribution from both leading particles and unified hydrodynamics is then compared against the experimental data performed in a wide now available center-of-mass energy region from 23.6 to 7000 GeV. The model predictions are in well consistent with experimental measurements.
