Observation of $Au+Au\to Au+Au+{\rho }^0$ and $Au+Au\to A{u}^{\ast }+A{u}^{\ast }+{\rho }^0$ with STAR

Abstract

We report the first observation of the reactions $Au+Au\to Au+Au+{\rho }^0$ and $Au+Au\to A{u}^{\ast }+A{u}^{\ast }+{\rho }^0$ with the STAR detector. The $\rho$ are produced at small perpendicular momentum, as expected if they couple coherently to both nuclei. We discuss models of vector meson production and the correlation with nuclear breakup, and present a fundamental test of quantum mechanics that is possible with the system.
