Description
With increasing beam energies the angular momentum of the fireball in peripheral heavy ion collisions is increasing. The earlier predicted rotation effect and Kelvin Helmholtz Instability, leads to space-time momentum correlations among the emitted particles. For these reactions two particle correlations are studied. A specific combination of two particle correlation measurements is proposed, the Differential Hanbury Brown and Twiss method, which can sensitively detect the rotation of the emitting system. In case of azimuthally symmetric systems without rotation the new method gives zero signal, while it is sensitive to the rotation in the system. The method is studied in simple models and in numerical fluid dynamic model results.
