“…radial hydrodynamical flow [37,38]). In heavy ion collisions, strong correlations have been observed between pairs of hadrons [39][40][41][42], characterized by a ridge shape, very elongated in the relative rapidity of the two particles, and peaked in their relative azimuthal angle. By causality, the correlations in rapidity have to be created in the very early stages of the collisions [43], and they can be simply understood as a consequence of the near boost invariance of the sources of the incoming nuclei.…”

“…At leading order, it can still be expressed in terms of the Fourier coefficients of a pair of solutions of the classical equation of motion, via eq. (39). However, because we must now set z(p) = 0 in the boundary conditions (37) for these classical fields, they are not retarded fields anymore 8 , and there is no practical way to calculate them.…”

“…The discovery of the long-range rapidity correlation known as the 'ridge' in heavy ion collisions at the Relativistic Heavy Ion Collider (RHIC) [2][3][4][5] spurred, among other things, a flurry of activity [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21] aimed at better understanding two-particle correlations in the parton saturation/Color Glass Condensate (CGC) physics framework (see [22][23][24][25][26][27] for reviews of the saturation/CGC field). Apart from quantifying how much of the 'ridge' dynamics, which in the meantime was also observed by experiments at the Large Hadron Collider (LHC) in proton-proton (pp) and protonnucleus (pA) collisions [28][29][30][31], is due to the initial-state saturation effects, the problem of two-gluon production in nucleus-nucleus (AA) collisions is an important theoretical problem in its own right, allowing us to gain a new insight in the nonlinear dynamics of strong gluon fields in the initial stages of heavy ion collisions.…”

Two-gluon correlations in heavy–light ion collisions: Energy and geometry dependence, IR divergences, and kT-factorization

We study the properties of the cross section for two-gluon production in heavy-light ion collisions derived in our previous paper [1] in the saturation/Color Glass Condensate framework. Concentrating on the energy and geometry dependence of the corresponding correlation functions we find that the two-gluon correlator is a much slower function of the center-of-mass energy than the one-and two-gluon production cross sections. The geometry dependence of the correlation function leads to stronger azimuthal near-and away-side correlations in the tip-on-tip U+U collisions than in the side-on-side U+U collisions, an exactly opposite behavior from the correlations generated by the elliptic flow of the quark-gluon plasma: a study of azimuthal correlations in the U+U collisions may thus help to disentangle the two sources of correlations.We demonstrate that the cross section for two-gluon production in heavy-light ion collisions contains a power-law infrared (IR) divergence even for fixed produced gluon momenta: while saturation effects in the target regulate some of the power-law IR divergent terms in the lowest-order expression for the two-gluon correlator, other power-law IR divergent terms remain, possibly due to absence of saturation effects in the dilute projectile. Finally we rewrite our result for the two-gluon production cross-section in a kT -factorized form, obtaining a new factorized expression involving a convolution of one-and two-gluon Wigner distributions over both the transverse momenta and impact parameters. We show that the two-gluon production cross-section depends on two different types of unintegrated two-gluon Wigner distribution functions.

“…The strength of the long-range correlation is quantified by the per-trigger yield function, Y(|∆φ|), which measures the correlation between two particles in a restricted ∆η range at a given |∆φ|. Its minimum value is fixed to zero by subtracting a value of the ZYAM-determined [57] The < N part > dependence of < v n > (left panels), σ vn (middle panels) and σ vn / < v n > (right panels) for n = 2 (top row), n = 3 (middle row) and n = 4 (bottom row) [20]. Each panel shows the results for three p T ranges together with the total systematic uncertainties.…”

An overview of the results on anisotropic particle flow in lead-lead collisions at √ s NN = 2.76 TeV and proton-lead collisions at √ s NN = 5.02 TeV obtained with the ATLAS detector at the Large Hadron Collider is presented. The final-state anisotropy is studied by measuring the Fourier harmonics (v n ) of the azimuthal angle distributions of produced charged particles. A large anisotropy in the azimuthal angle distribution of particles produced in Pb+Pb collisions is measured, providing new constraints on the initial geometry models and on hydrodynamic evolution of the system. The same analysis methods have been also applied to study modulations in the azimuthal angle distributions of particles produced in p+Pb collisions. The obtained results are indicative of the importance of final-state effects in small collision systems which may lead to collective flow similar to that observed in the dense and hot system created in Pb+Pb collisions.
