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

Spencer Klein

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…
