In this paper we investigate how the energy and momentum deposited by partonic dijets in the quark-gluon plasma may affect the direct, elliptic and triangular flow of low (and intermediate) $p_T$ hadrons in central Au+Au collisions at RHIC. The dijets are modeled as external sources in the energy-momentum conservation equations for hydrodynamics, which are solved on an event-by-event basis within the ideal fluid approximation. We focus our investigation at mid-rapidity and solve the hydrodynamic equations imposing boost invariance. Differential anisotropic flow coefficients for $p_T \gtrsim 1$ GeV are found to be significantly enhanced if the dijets deposit on average more than 12 GeV in the QGP (or more than 6 GeV per jet). Because this jet-induced extra anisotropic flow is not related to the fluctuations of the initial geometry of the collision, the correlation between the $v_2$ and $v_3$ coefficients and their corresponding eccentricities is considerably weakened. In addition, we argue that the extra amount of direct flow induced by dijets may be quantified by comparing the azimuthal dependence of dihadron correlations in dijet events with the corresponding quantity obtained in events without dijets. This comparison could be used to give a rough estimate of the magnitude of the effective coupling between the jets and the medium.

In this paper we investigate how the energy and momentum deposited by partonic dijets in the quark-gluon plasma may affect the direct, elliptic and triangular flow of low (and intermediate) $p_T$ hadrons in central Au+Au collisions at RHIC. The dijets are modeled as external sources in the energy-momentum conservation equations for hydrodynamics, which are solved on an event-by-event basis within the ideal fluid approximation. We focus our investigation at mid-rapidity and solve the hydrodynamic equations imposing boost invariance. Differential anisotropic flow coefficients for $p_T \gtrsim 1$ GeV are found to be significantly enhanced if the dijets deposit on average more than 12 GeV in the QGP (or more than 6 GeV per jet). Because this jet-induced extra anisotropic flow is not related to the fluctuations of the initial geometry of the collision, the correlation between the $v_2$ and $v_3$ coefficients and their corresponding eccentricities is considerably weakened. In addition, we argue that the extra amount of direct flow induced by dijets may be quantified by comparing the azimuthal dependence of dihadron correlations in dijet events with the corresponding quantity obtained in events without dijets. This comparison could be used to give a rough estimate of the magnitude of the effective coupling between the jets and the medium.

High-pT elliptic flow in a hydrodynamics-plus-jet-quenching simulation deviates from perfect linear scaling with soft elliptic flow, and a new cumulant-ratio observable is proposed to measure the deviation.

In few words, the procedure to compute an observable event-by-event, including the jet parametrization, is the following: (i) the initial conditions for hydrodynamics are computed using an implementation of the Monte Carlo Glauber model [ref] ; (ii) the initial position of the dijet (one dijet per event) is chosen on the mid-rapidity transverse plane (see the details in Ref. [ref] ); (iii) the dijet azimuthal angle in chosen isotropically; (iv) the initial jet transverse energy $E_T^ jet$ (the same for both jets in the pair) is chosen according to the jet yield per event in p+p collisions scaled by the number of binary collisions in Au+Au collisions [ref] ; (v) the hydrodynamic evolution is computed through the SPH method [ref] and (vi) the final spectra (for direct positively charged pions) is computed using the Cooper-Frye prescription [ref] .

First, we allow the jets to lose more and more energy and momentum in the medium and try to see how much is necessary to disconnect the flow parameters ${v_n,Ψ_n }$, as a function of $p_T$, from the initial geometric parameters ${ε_m,n,Φ_m,n }$, the $n$th eccentricity and the corresponding phase (for a discussion of how the flow parameters are related to the geometry of the initial conditions for hydrodynamics, see for instance Refs. [ref] ).
