Query: Chemical Equilibration at the Hagedorn Temperature   One important question in relativistic heavy ion collisions is if hadrons,
specifically anti-hyperons, are in equilibrium before thermal freezeout because
strangeness enhancement has long been pointed to as a signature for Quark Gluon
Plasma. Because anti-baryons have long equilibration times in the hadron gas
phase it has been suggested that they are "born" into equilibrium. However,
Hagedorn states, massive resonances, which are thought to appear near the
critical temperature, contribute to fast chemical equilibration times for a
hadron gas by providing extra degrees of freedom. Here we use master equations
to describe the interplay between Hagedorn resonances, pions, and baryon
anti-baryon pairs as they equilibrate over time and observe if the baryons and
anti-baryons are fully equilibrated within the fireball.
