“…This is done in order to have a more uniform detector performance within |η| < 1.0. The centrality definition, which is based on the raw charged particle TPC multiplicity with |η| < 0.5, is the same as that used previously [37]. After quality cuts, the number of the 60% most central events is about 24 million for 200 GeV Cu + Cu collisions and 10 million for 62.4 GeV Cu + Cu collisions.…”

We present the results of an elliptic flow, v 2 , analysis of Cu + Cu collisions recorded with the solenoidal tracker detector (STAR) at the BNL Relativistic Heavy Ion Collider at √ s NN = 62.4 and 200 GeV. Elliptic flow as a function of transverse momentum, v 2 (p T ), is reported for different collision centralities for charged hadrons h ± and strangeness-ontaining hadrons K 0 S , , , and φ in the midrapidity region |η| < 1.0. Significant reduction in systematic uncertainty of the measurement due to nonflow effects has been achieved by correlating particles at midrapidity, |η| < 1.0, with those at forward rapidity, 2.5 < |η| < 4.0. We also present azimuthal correlations in p + p collisions at (2010) energy, m T − m, and (ii) at intermediate p T , 2 < p T < 4 GeV/c, it scales with the number of constituent quarks, n q . We have found that ideal hydrodynamic calculations fail to reproduce the centrality dependence of v 2 (p T ) for K 0 S and . Eccentricity scaled v 2 values, v 2 /ε, are larger in more central collisions, suggesting stronger collective flow develops in more central collisions. The comparison with Au + Au collisions, which go further in density, shows that v 2 /ε depends on the system size, that is, the number of participants N part . This indicates that the ideal hydrodynamic limit is not reached in Cu + Cu collisions, presumably because the assumption of thermalization is not attained.

“…This correlation was established from a Monte Carlo Glauber simulation [40][41][42] using, as an input, the Woods-Saxon nuclear-matter density for the gold ion [43] and the Hulthén wave function of the deuteron [44]. In this simulation, the inelastic cross section for a nucleon-nucleon collision was taken to be σ NN inel = 42 mb.…”

We report a measurement of high-p T inclusive π 0 , η, and direct photon production in p + p and d + Au collisions at √ s NN = 200 GeV at midrapidity (0 < η < 1). Photons from the decay π 0 → γ γ were detected in the barrel electromagnetic calorimeter of the STAR experiment at the Relativistic Heavy Ion Collider. The η → γ γ decay was also observed and constituted the first η measurement by STAR. The first direct photon cross-section measurement by STAR is also presented; the signal was extracted statistically by subtracting the π 0 , η, and ω(782) decay background from the inclusive photon distribution observed in the calorimeter. The analysis is described in detail, and the results are found to be in good agreement with earlier measurements and with next-to-leading-order perturbative QCD calculations.

“…These findings are derived from the observation of elliptic flow [12][13][14][15][16], electromagnetic spectra [17,18], quarkonium melting [19][20][21][22][23][24][25][26], enhanced strangeness production [27][28][29][30][31][32] and jet quenching [33][34][35][36][37][38][39][40][41][42][43][44]; for a very recent review, see ref.

We present a lattice study of the equation of state in Yang-Mills theory based on the exceptional G 2 gauge group. As is well-known, at zero temperature this theory shares many qualitative features with real-world QCD, including the absence of colored states in the spectrum and dynamical string breaking at large distances. In agreement with previous works, we show that at finite temperature this theory features a first-order deconfining phase transition, whose nature can be studied by a semi-classical computation. We also show that the equilibrium thermodynamic observables in the deconfined phase bear striking quantitative similarities with those found in SU(N ) gauge theories: in particular, these quantities exhibit nearly perfect proportionality to the number of gluon degrees of freedom, and the trace anomaly reveals a characteristic quadratic dependence on the temperature, also observed in SU(N ) Yang-Mills theories (both in four and in three spacetime dimensions). We compare our lattice data with analytical predictions from effective models, and discuss their implications for the deconfinement mechanism and high-temperature properties of strongly interacting, non-supersymmetric gauge theories. Our results give strong evidence for the conjecture that the thermal deconfining transition is governed by a universal mechanism, common to all simple gauge groups.
