Multi-particle critical correlations

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...

Negative Correlations and Particle Systems

Critical visibility for N-particle Greenberger-Horne-Zeilinger correlations to violate local realism

A sequence of Bell inequalities for N -particle systems, which involve three settings of each of the local measuring apparatuses, is derived. For GHZ states, quantum mechanics violates these inequalities by factors exponentially growing with N . The threshold visibilities of the multiparticle sinusoidal interference fringes, for which local realistic theories are ruled out, decrease as (2/3)N ....

Velocity Correlations of a Brownian Particle Velocity Correlations of a Brownian Particle

A new derivation of the velocity correlations of a thermally fluctuating Brownian particle is shown by direct calculation from a stochastic hydrodynamic model in which the fluid-particle coupling is treated in a simple manner. The model significantly simplifies the calculation of statistics of a particle and has the virtue of being readily amenable to numerical simulation. To show that the mode...

Spin determination of particle unstable levels with particle correlations

Experiments with rare isotope and with stable beams offer important opportunities to explore the structure of nuclei near and beyond the proton and neutron drip lines. This structure information includes the energies, spins, and parities of nuclear levels near the drip line as well as the probabilities for their formation and decay; such information guides theoretical modeling of the interactio...
