Abstract.

Due to long chemical equilibration times of hadrons in the hadron gas phase in relativistic heavy ion collisions it has been suggested that they are “born" into equilibrium. Here we review reactions that allow for quick equilibration times within the hadron gas phase such as multi-mesonic reactions at SpS and Hagedorn resonances decays at RHIC. The inclusion of a Bjorken expansion reveals that baryon anti-baryon pairs can quickly equilibrate within the hadron gas phase.
