Multi-strange hadrons and the precision extraction of QGP properties in   the RHIC-BES domain
  We systematically compare an event-by-event transport+viscous hydrodynamics hybrid model to data from the RHIC beam energy scan using a general Bayesian method. We demonstrate how the inclusion of multistrange hadron observables affects the outcome of the Bayesian analysis and conduct an in depth analysis of the viability of $\phi$ and $\Omega$ as probes of the transition region between a deconfined quark-gluon plasma and hadronic phase in heavy ion collisions at higher-end RHIC collision energies. Utilizing UrQMD to model the final hadronic interactions, we examine the collision rates of $\phi$ and $\Omega$ and the modification to their transverse momentum spectra due to these interactions.
