Transverse momentum spectra and elliptic flow: Hydrodynamics with QCD-based equations of state
نویسنده
چکیده
We present a family of equations of state within a quasiparticle model adjusted to lattice QCD and study the impact on azimuthal flow anisotropies and transverse momentum spectra within hydrodynamic simulations for heavyion collisions at energies relevant for LHC.

Eccentricity fluctuations in an integrated hybrid approach: Influence on elliptic flow
The effects of initial state fluctuations on elliptic flow are investigated within a (3 + 1)-dimensional Boltzmann + hydrodynamics transport approach. The spatial eccentricity ( RP and part) is calculated for initial conditions generated by a hadronic transport approach (ultrarelativistic quantum molecular dynamics). Elliptic flow results as a function of impact parameter, beam energy, and tran...
متن کاملWhat can we learn from hydrodynamic analysis of elliptic flow ? ∗
Recently, physicists at Brookhaven National Laboratory made an announcement that “RHIC serves the perfect liquid” [ 1]. The agreement of hydrodynamic predictions [ 2] of integrated and differential elliptic flow and radial flow patterns with Au+Au data at RHIC energies [ 3, 4, 5, 6] is one of the main lines of the announcement. We first study the sensitivity of this conclusion to different hydr...
متن کاملDescribing transverse dynamics and space-time evolution at RHIC in a hydrodynamic model with statistical hadronization
A hydrodynamic model coupled to the statistical hadronization code Therminator is used to study a set of observables in the soft sector at RHIC. A satisfactory description of the p⊥-spectra and elliptic flow is obtained, similarly to other hydrodynamic models. With the Gaussian initial conditions the transverse femtoscopic radii are also reproduced, providing a possible solution of the RHIC HBT...
متن کاملElliptic flow from partially thermalized heavy - ion collisions ∗
We study to what extent the measured elliptic flow at RHIC constrains viscous deviations from ideal hydrodynamics. We solve a toy model where only transverse momenta are thermalized while the system undergoes longitudinal free-streaming. We show that RHIC data exclude such a model and thus require fast 3-dimensional thermalization. One of the most important discoveries at RHIC so far has been t...
متن کاملResonance recombination model and quark distribution functions in the quark-gluon plasma
We investigate the consequences of space-momentum correlations in quark phase-space distributions for coalescence processes at the hadronization transition. Thus far it has been proved difficult to reconcile such correlations with the empirically observed constituent quark number scaling (CQNS) at the Relativistic Heavy Ion Collider (RHIC). To address this problem we combine our earlier develop...
