“…More recently m T -scaling has been mentioned [10,11] in the context of the possible formation of a 'colour glass condensate' in heavy-ion collisions [12,13]. In this light, we wish to test the same scaling on our data.…”

“…Protons and antiprotons produced via a baryon-junction mechanism combined with jet quenching for pions exhibit the same effect [570]. Intrinsic p t -broadening in the partonic phase caused by the gluon saturation expected in high-density QCD [571] is an alternative explanation.…”

ALICE is a general-purpose heavy-ion experiment designed to study the physics of strongly interacting matter and the quark–gluon plasma in nucleus–nucleus collisions at the LHC. It currently includes more than 900 physicists and senior engineers, from both nuclear and high-energy physics, from about 80 institutions in 28 countries.The experiment was approved in February 1997. The detailed design of the different detector systems has been laid down in a number of Technical Design Reports issued between mid-1998 and the end of 2001 and construction has started for most detectors.Since the last comprehensive information on detector and physics performance was published in the ALICE Technical Proposal in 1996, the detector as well as simulation, reconstruction and analysis software have undergone significant development. The Physics Performance Report (PPR) will give an updated and comprehensive summary of the current status and performance of the various ALICE subsystems, including updates to the Technical Design Reports, where appropriate, as well as a description of systems which have not been published in a Technical Design Report.The PPR will be published in two volumes. The current Volume I contains: a short theoretical overview and an extensive reference list concerning the physics topics of interest to ALICE, relevant experimental conditions at the LHC, a short summary and update of the subsystem designs, and a description of the offline framework and Monte Carlo generators. Volume II, which will be published separately, will contain detailed simulations of combined detector performance, event reconstruction, and analysis of a representative sample of relevant physics observables from global event characteristics to hard processes.

“…Preliminary analysis of STAR experiment d+Au collision data (Figure 4) shows a generalized m T scaling for various particles at low p T . Such a scaling is predicted from a color glass condensate scenario in the initial state [ 16]. Furthermore, the (p + p)/(π + + π − ) ratio from quark jets in e + + e − collisions are lower compared to those from Au+Au collisions [ 7].…”

The non-Abelian feature of quantum chromodynamics (QCD) results in the gluons losing more energy than quarks in the medium formed in high energy heavy-ion collisions. Experimental results in p+p collisions when compared to NLO pQCD calculations show that at high transverse momentum (p T ) the produced protons+anti-protons are dominantly from gluon jets and charged pions have substantial contribution from quark jets. If such a scenario is applied to heavy-ion collisions at RHIC, one would expect the difference in quark and gluon energy loss to have an effect on measured observables, such as high p T p(p)/π ratios and the nuclear modification factor for various particles species. We discuss the experimental results and some possible future measurements.
