Title: Observables for longitudinal flow correlations in heavy-ion collisions

Abstract

In this paper, we propose several new observables/correlators, based on correlations between two or more subevents separated in pseudorapidity η, to study the longitudinal flow fluctuations. We show that these observables are sensitive to the event-by-event fluctuations, as a function of η, of the initial condition as well as the nonlinear mode-mixing effects. Finally, experimental measurement of these observables shall provide important new constraints on the boost-variant event-by-event initial conditions required by all 3+1-dimensional viscous hydrodynamics models.

  • Using 4{pi} data from the Bevalac streamer chamber, we study azimuthal correlations for fragment pairs and higher-order multiplets. We point out that previous studies of sideward flow have not ruled out the possibility that the effect is dominated by a small number of correlated fragments in each event, as opposed to being a collective motion to which most or all fragments contribute. Based on a simulation, we infer that more than 70% of the forward-going fragments from collisions of Ar on Pb at 0.4{ital A} GeV carry a component of the collective motion.
  • We present a new type of flow analysis, based on a particle-pair correlation function, in which there is no need for an event-by-event determination of the reaction plane. Consequently, the need to correct for dispersion in an estimated reaction plane does not arise. Our method also offers the option to avoid any influence from particle misidentification. Using this method, streamer chamber data for collisions of Ar+KCl and Ar+BaI{sub 2} at 1.2 GeV/nucleon are compared with predictions of a nuclear transport model.
  • High transverse momentum (P{sub T}) {gamma}-hadron correlations are currently being regarded as the 'golden channel' for the study of the medium produced in ultrarelativistic heavy-ion collisions by means of hard probes. This is for several reasons, all linked to the fact that because of the smallness of the electromagnetic coupling {alpha}, the photon does not substantially interact with the medium and is expected to escape unmodified. Thus, a high P{sub T} photon indicates a hard process in the collision independent of the position of the hard vertex. In contrast, there may not be a clear signal for a hard processmore » involving strongly interacting partons if the production vertex is deep in the medium as both partons undergo substantial final state interaction. Equally important, if photon production by fragmentation can be separated experimentally, the photon provides almost full knowledge of the initial kinematics. In the present paper, these properties are used to demonstrate a distinguishing feature between two assumptions made in modeling the medium modifications of strongly interacting high P{sub T} processes: loss of energy into the medium vs medium modification of the partonic shower. It is shown that {gamma}-hadron correlations provide a very clean signature for distinguishing the two scenarios.« less
  • Using the AMPT model for relativistic heavy ion collisions, we have studied the di-hadron azimuthal angular correlations triggered by emitted jets in Au+Au collisions at center-of-mass energy {radical}(s{sub NN})=200 GeV and impact parameter b=8 fm. A double-peak structure for the associated particles at the away side of trigger particles is obtained after subtracting background correlations due to the elliptic flow. Both the near-side peak and the away-side double peaks in the azimuthal angular correlations are, however, significantly suppressed (enhanced) in events of small (large) triangular flow or triangularity in the initial collision geometry as a result of fluctuations. After subtractionmore » of background correlations due to the triangular flow, the away-side double peaks change into a single peak with broad shoulders on both sides. The away side of the di-hadron correlations becomes essentially a single peak after further subtraction of higher-order flows.« less
