A hybrid model that employs the hadron-string transport model UrQMD and the (3+1)D relativistic viscous hydrodynamic code vHLLE, is used to investigate the beam energy dependence of the correlation coefficient ρ(v 2 2 , [pT ]) between the average transverse momentum [pT ] of hadrons emitted in an event and the square of the anisotropic flow coefficient v 2 2 . For Au+Au collisions, the model predicts characteristic patterns for the energy and event-shape dependence of the variances for [pT ] and v 2 n (Var([pT ]) and Var(v 2 2 )), and the covariance of v 2 n and [pT ] (cov(v 2 2 , [pT ])), consistent with the attenuation effects of the specific shear viscosity η/s. In contrast, ρ(v 2 2 , [pT ]) is predicted to be insensitive to the beam energy but sensitive to the initial-state geometry of the collisions. These observations suggest that a precise set of measurements for Var ([pT ]), Var(v 2 2 ), cov(v 2 2 , [pT ]) and ρ(v 2 2 , [pT ]) as a function of beam-energy and event-shape, could aid precision extraction of the temperature and baryon chemical-potential dependence of η/s from the wealth of Au+Au data obtained in the RHIC beam energy scan.

“…The reason is that the AMPT model fails to describe the radial flow and its fluctuations [34]. In fact we found AMPT underestimates the var([p T ]) data [35] for Au+Au at RHIC by more than factor of two, and this problem is there for all recent versions of AMPT. This failure implies that radial flow response to the size of the system is too weak in AMPT.…”

Probing nuclear quadrupole deformation from correlation of elliptic flow and transverse momentum in heavy ion collisions

In heavy ion collisions, elliptic flow v2 and radial flow, characterized by event-wise average transverse momentum [p T ], are related to the shape and size of the overlap region, which are sensitive to the shape of colliding atomic nuclei. The Pearson correlation coefficient between v2 and [p T ], ρ2, was found to be particularly sensitive to the quadrupole deformation parameter β that is traditionally measured in low energy experiments. Built on earlier insight that the prolate deformation β > 0 reduces the ρ2 in ultra-central collisions (UCC), we show that the prolate deformation β < 0 enhances the value of ρ2. As β > 0 and β < 0 are the two extremes of triaxiality, the strength and sign of v 2 2 − [p T ] correlation can be used to provide valuable information on the triaxiality of the nucleus. Our study provide further arguments for using the hydrodynamic flow as a precision tool to directly image the deformation of the atomic nuclei at extremely short time scale (< 10 −24 s).

“…the centrality dependence of average transverse momentum ⟪p T ⟫ ≡ ⟨[p T ]⟩ and the variance ⟨(δ[p T ]) 2 ⟩ do not describe the experimental data [14,51]. A recent modification of the model [52] fixed the problem with the ⟪p T ⟫, but the value of ⟨(δ[p T ]) 2 ⟩ is still more than a factor of 3 lower than the STAR data [21,53] 2 . This implies that the response of [p T ] to d ⊥ in AMPT is a lot weaker than experimental finding, this probably is also the reason why the model underestimates quantitatively the sign-change of ⟨v 2 2 δ[p T ]⟩ in U+U collisions associated with the large prolate deformation Uranium nucleus observed by the STAR data [21].…”

Probing triaxial deformation of atomic nuclei in high-energy heavy ion collisions

Most atomic nuclei are deformed with a quadrupole shape described by its overall strength β2 and triaxiality γ. The deformation can be accessed in high-energy heavy-ion collisions by measuring the collective flow response of the produced quark-gluon plasma to the eccentricity ε2 and the density gradient d⊥ in the initial state. Using analytical estimate and a Glauber model, we show that the variances, ⟨ε 2 2 ⟩ or ⟨(δd⊥ d⊥) 2 ⟩, and skewnesses, ⟨ε 2 2 δd⊥ d⊥⟩ or ⟨(δd⊥ d⊥From these, we constructed several normalized skewnesses to isolate the γ dependence from that of β2, and show that the correlations between a normalized skewness and a variance can constrain simultaneously the β2 and γ. Assuming a linear relation with elliptic flow v2 and mean-transverse momentum [p T ] of final state particles, v2 ∝ ε2 and δd⊥ d⊥ ∝ δ[p T ] [p T ], similar conclusions are also expected for the variances and skewnesses of v2 and [p T ], which can be measured precisely in top RHIC and LHC energies. Our findings motivate a dedicated system scan of high-energy heavy ion collisions to measure triaxiality of atomic nuclei. This is better done by collisions of prolate, cos(3γ) = 1, and oblate nuclei, cos(3γ) = −1, with well known β2 values to calibrate the coefficients b ′ and c ′ , followed by collisions of species of interest especially those with known β2 but unknown γ.
