We study the effect of strong longitudinal color fields (SCF) in p+p reactions up to Large Hadron Collider energies in the framework of the HIJING/BB v2.0 model that combines (collinear factorized) pQCD multiple minijet production with soft longitudinal string excitation and hadronization.The default vacuum string tension, κ 0 = 1 GeV/fm, is replaced by an effective energy dependent string tension, κ(s) = κ 0 (s/s 0 ) 0.06 that increases monotonically with center-of-mass energy. The exponent λ = 0.06 is found sufficient to reproduce well the energy dependence of multiparticle observables in RHIC, Tevatron, as well as recent LHC data. This exponent is half of that predicted by the Color Glass Saturation (CGC) model, λ CGC = 0.115, where gluon fusion multiparticle production mechanisms are assumed. In HIJING/BB v2.0, the rapid growth of dN ch /dη with energy is due to the interplay of copious minijet production with increasing of strong color field (SCF) contributions. The large (strange)baryon-to-meson ratios measured at Tevatron energies are well described. A significant enhancement of these ratios is predicted up to the highest LHC energy (14 TeV). The effect of JJ loops and SCF on baryon-anti-baryon asymmetry, and its relation to baryon number transport, is also discussed.PACS numbers: 12.38. Mh, 24.85.+p, 25.40Ve, 1

The PHOBOS perspective on discoveries at RHIC

This paper describes the conclusions that can be drawn from the data taken thus far with the PHOBOS detector at RHIC. In the most central Au+Au collisions at the highest beam energy, evidence is found for the formation of a very high energy density system whose description in terms of simple hadronic degrees of freedom is inappropriate. Furthermore, the constituents of this novel system are found to undergo a significant level of interaction. The properties of particle production at RHIC energies are shown to follow a number of simple scaling behaviors, some of which continue trends found at lower energies or in simpler systems. As a function of centrality, the total number of charged particles scales with the number of participating nucleons. When comparing Au+Au at different centralities, the dependence of the yield on the number of participants at higher p T (∼4 GeV/c) is very similar to that at low transverse momentum. The measured values of charged particle pseudorapidity density and elliptic flow were found to be independent of energy over a broad range of pseudorapidities when effectively viewed in the rest frame of one of the colliding nuclei, a property we describe as "extended longitudinal scaling". Finally, the centrality and energy dependences of several observables were found to factorize to a surprising degree.

A thermal model, based on the Tsallis distribution and blast-wave model, is proposed to compute hadron double-differential spectra d 2 N/dpTdy in pp (also high-energy pp) collisions. It successfully describes the available experimental data on pion and quarkonia (φ, J/ψ, ψ(2S), Υ family) production at energies from √ s = 5 GeV to the LHC ones. Simple parametrizations for the √ s dependence of the model parameters are provided allowing predictions for the yields of these particles at new collision energies. The model can be used also for the pion Bose-Einstein correlation studies.PACS numbers: 24.10. Pa, 13.85.Ni, 25.75.-q * Smbat.Grigoryan@cern.ch 1 There are hundreds of papers that develop and/or use such models. We cite only some of them which include further references.
