Event-Shape-Dependent Analysis of Charm–Anticharm Azimuthal Correlations in Simulations

Event Shape/Energy Flow Correlations

We introduce a set of correlations between energy flow and event shapes that are sensitive to the flow of color at short distances in jet events. These correlations are formulated for a general set of event shapes, which includes jet broadening and thrust as special cases. We illustrate the method for e+e− dijet events, and calculate the correlation at leading logarithm in the energy flow and a...

Three-Particle Azimuthal Correlations

Two-particle azimuthal correlations in central Au+Au collisional at RHIC have revealed a broadened away-side structure, with respect to perpherial Au+Au, pp, and d+Au. This could be explained by different physics mechanisms such as: large angle gluon radiation, deflected jets, Ĉerenkov gluon radiation, and conical flow generated by hydrodynamic shock-waves. We can discriminate the scenarios wit...

Interjet Energy Flow/Event Shape Correlations

We identify a class of perturbatively computable measures of interjet energy flow, which can be associated with well-defined color flow at short distances. As an illustration, we calculate correlations between event shapes and the flow of energy, QΩ, into an interjet angular region, Ω, in high-pT twojet ee-annihilation events. Laplace transforms with respect to the event shapes suppress states ...
