Measuring shear viscosity using transverse momentum correlations in relativistic nuclear collisions.
Elliptic flow measurements at the Brookhaven National Laboratory Relativistic Heavy Ion Collider suggest that quark-gluon fluid flows with very little viscosity compared to weak-coupling expectations, challenging theorists to explain why this fluid is so nearly "perfect." It is therefore vital to find quantitative experimental information on the viscosity of the fluid. We propose that measureme...
متن کاملTwo particle rapidity, transverse momentum, and azimuthal correlations in relativistic nuclear collisions and transverse radial expansion
At the very first stage of an ultra-relativistic nucleus-nucleus collision new particles are produced in individual nucleon-nucleon collisions. In the transverse plane, all particles from a single NN collision are initially located at the same position. The subsequent transverse radial expansion of the system creates strong position-momentum correlations and leads to characteristic rapidity, tr...
متن کاملEstimation of shear viscosity based on transverse momentum correlations
Event anisotropy measurements at RHIC suggest the strongly interacting matter created in heavy ion collisions flows with very little shear viscosity. Precise determination of “shear viscosityto-entropy” ratio is currently a subject of extensive study [1]. We present preliminary results of measurements of the evolution of transverse momentum correlation function with collision centrality of Au +...
متن کاملMomentum-Multiplicity Correlations in Relativistic Heavy Ion Collisions
My REU project focused on high-energy nuclear collisions. I collaborated with past REU student Michael Catanzaro and faculty mentor Sean Gavin to study momentum-multiplicity correlations. This work extends work performed last year by Catanzaro in two ways (see Catanzaro’s REU report from summer 2009 on this web site). First, I studied pion and kaon distributions to see how correlations appear i...
