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.

Investigations have shown that the collective motion not only appears in nucleus-nucleus but also in p-p collisions. The best tool for depicting such collective motion is relativistic hydrodynamics. In this paper, the collective motion is assumed obeying the hydro model which integrates the features of Landau and Hwa-Bjorken theory and is one of a very few analytically solvable models. The fluid is then supposed freezing out into charged particles from a time-like hypersurface with a fixed time of FO t . The researches of present paper show that this part of charged particles together with leading particles, which, by conventional definition, carry on the quantum numbers of colliding nucleons and take away the most part of incident energy, can give a proper universal description to the pseudorapidity distributions of charged particles measured in both nucleus-nucleus and p-p collisions at now available energy regions. PACS number(s): 25.75.Ag, 25.75.Ld, 24.10.Nz Ⅰ. IntroductionIn recent years, especially with the operations of BNL-RHIC and after CERN-LHC, the natures of matter created in nucleus or particle collisions have been undergoing a wide experimental and theoretical research. One of the most important achievements arrived at from this research is that the quark-gluon plasma formed in collisions is in a strongly coupled state as fluid, instead of being in a conventionally believed state as weakly interacting partonic gas [1][2][3][4][5]. The investigations also have shown that this kind of strongly coupled quark-gluon plasma has not only been created in nucleus but also in particle, such as p-p collisions, and the motion of this partonic fluid is nearly as an ideal one with a very little viscosity .The best approach for describing the spatiotemporal evolution of fluid-like partonic matter is the relativistic hydrodynamics, which was first put forward by L. D. Landau in his pioneering work in 1953 [35]. Owing to the high degree of nonlinearity and interconnection of hydro equations, Monte Carlo simulations is, as usual, widely employed to deal with them especially for 2 or 3-dimensional expansions or situations including viscosity.

“…One is that the quark-gluon plasma (QGP) might have come into being in nucleus collisions at current RHIC or LHC energies [11] [12] [13] [14] [15]. This also might be true even in hadron collisions at the early lower energies of Intersecting Storage Rings (ISR) and Super Proton Synchrotron (SPS) at CERN [16] [17] [18] [19] [20]. The other is that the matter created in nucleus or hadron collisions shows a clear feature of collective flow, expanding cal feature of this theoretical model is that it incorporates the effects of phase transition into solutions.…”

It is widely believed that the matter created in p-p collisions exhibits a similar collective behavior as that formed in heavy ion collisions. In this paper, by taking into account the effects of thermal motion, the transverse momentum distributions of identified charged particles are discussed in the scope of the hydrodynamic model including phase transition. The theoretical model gives a good description to the data collected in p-p collisions at LHC energies for the transverse momentum up to about 1.0 GeV T p c = .
