This writeup is a compilation of the predictions for forthcoming Heavy Ion Program at Large Hadron Collider, as presented CERN Theory Institute 'Heavy Collisions LHC - Last Call Predictions', held from May 14th to June 10th 2007.
This report is based on a ten-week program Gluons and the quark sea at high-energies, which took place Institute for Nuclear Theory (INT) in Seattle Fall 2010. The principal aim of was to develop sharpen science case an Electron-Ion Collider (EIC), facility that will be able collide electrons positrons with polarized protons light heavy nuclei high energies, offering unprecedented possibilities in-depth studies quantum chromodynamics (QCD). organized around following four major themes: (i)...
This White Paper presents an overview of the current status and future perspective QCD research, based on community inputs scientific conclusions from 2022 Hot Cold Town Meeting. We present progress made in last decade toward a deep understanding both fundamental structure sub-atomic matter nucleon nucleus cold QCD, hot heavy ion collisions. identify key questions research plausible paths to obtaining answers those near future, hence defining priorities our over coming decades.
We introduce a combined macroscopic-microscopic transport approach employing relativistic hydrodynamics for the early, dense, deconfined stage of reaction and microscopic nonequilibrium model later hadronic where equilibrium assumptions are not valid anymore. Within this we study dynamics hot, bulk QCD matter, which is expected to be created in ultrarelativistic heavy-ion collisions at Super Proton Synchrotron, Relativistic Heavy Ion Collider, Large Hadron Collider. Our capable...
We show that the centrality and system-size dependence of elliptic flow measured at BNL Relativistic Heavy Ion Collider (RHIC) are fully described by a simple model based on eccentricity scaling incomplete thermalization. argue is least 25% below (ideal) ``hydrodynamic limit,'' even for most central Au-Au collisions. This lack perfect equilibration allows estimates effective parton cross section in quark-gluon plasma its viscosity to entropy density ratio. also how initial conditions affect...

We consider the single-inclusive minijet cross section in pA at forward rapidity within color glass condensate model of high energy collisions. show that nucleus appears black to incident quarks except for very large impact parameters. A markedly flatter p(t) distribution as compared QCD dilute perturbative limit is predicted transverse momenta about saturation scale, which could be Q(2)(s) approximately 10 GeV2 a gold boosted (as BNL-RHIC).
Predictions for charged hadron, identified light quarkonium, photon, jet and gauge bosons in p+ Pb collisions at [Formula: see text] are compiled compared. When test run data available, they compared to the model predictions.
We determine the distribution of linearly polarized gluons a dense target at small x by solving Balitsky-Jalilian-Marian-Iancu-McLerran-Weigert-Leonidov-Kovner rapidity evolution equations. From these solutions, we estimate amplitude ∼cos2ϕ azimuthal asymmetries in deep inelastic scattering dijet production high energies. find sizable long-range with magnitude range v_{2}=⟨cos2ϕ⟩∼10%.
We investigate flow in semiperipheral nuclear collisions at Alternating Gradient Synchrotron and Super Proton energies within macroscopic as well microscopic transport models. The hot dense zone assumes the shape of an ellipsoid which is tilted by angle $\ensuremath{\Theta}$ with respect to beam axis. If matter close softest point equation state, this expands predominantly orthogonal direction given $\ensuremath{\Theta}.$ This antiflow component responsible for previously predicted reduction...
We discuss how to extract renormalized loops from bare Polyakov in $\mathrm{SU}(N)$ lattice gauge theories at nonzero temperature. Single an irreducible representation are multiplicatively renormalized, without mixing, through mass renormalization. The values of the four lowest representations $\mathrm{SU}(3)$ were measured numerically on small, coarse lattices. find that magnitude, condensates for sextet and octet approximately square triplet loop. This agrees with a large N expansion,...
The eccentricity in coordinate-space at midrapidity of the overlap zone high-energy heavy-ion collisions predicted by $k_\perp$-factorization formalism is generically larger than expected from scaling with number participants. We provide a simple qualitative explanation effect which shows that it not caused predominantly edge effects. also show quite insensitive to ``details'' unintegrated gluon distribution functions such as presence leading-twist shadowing and an extended geometric window....
We determine the hard-loop resummed propagator in an anisotropic QCD plasma general covariant gauges and define a potential between heavy quarks from Fourier transform of its static limit. find that there is stronger attraction on distance scales order inverse Debye mass for quark pairs aligned along direction anisotropy than transverse alignment.
We study the effect of dense quarks in a $SU(N)$ matrix model deconfinement. For three or more colors, quark contribution to loop potential is complex. After adding charge conjugate loop, measure integral real, but not positive definite. In model, act like background $Z(N)$ field; at nonzero density, field also has an imaginary part, proportional part loop. Consequently, while expectation values and its complex are both they equal. These results suggest possible approach fermion sign problem...
We determine viscosity corrections to the retarded, advanced and symmetric gluon self-energies static propagator in weak-coupling ``hard loop'' approximation high-temperature QCD. apply these results calculate imaginary part of heavy-quark potential which is found be smaller (in magnitude) than at vanishing viscosity. This implies a decay width quarkonium bound states an anisotropic plasma.
We consider quarkonium in a hot quantum chromodynamics (QCD) plasma which, due to expansion and nonzero viscosity, exhibits local anisotropy momentum space. At short distances the heavy-quark potential is known at tree level from hard-thermal loop resummed gluon propagator anisotropic perturbative QCD. The long modeled as QCD string which screened same scale Coulomb field. asymptotic separation energy inversely proportional temperature. obtain numerical solutions of three-dimensional...
