Description
We study the effect of the missing resonances from the hadron spectrum on the extracted freezeout temperatures and chemical potentials from data on particle yields. We study several decay schemes for these missing resonances and estimate their influence in different freezeout schemes like 1CFO (unified freezeout of all hadrons), 1CFO+$\gamma_S$ ($\gamma_S$ accounting for undersaturation of strangeness) and 2CFO (early freezeout of strangeness). Further, based on monotonicity of several thermodynamic quantities we provide a bound on the extent of the hadron resonance gas phase on the (T, \mu_B) plane. We also discuss how the missing resonances affect this bound.
Summary
We study the effect of the missing resonances from the hadron spectrum on the extracted freezeout temperatures and chemical potentials from data on particle yields as well as the extent of the hadron resonance gas phase on the QCD phase diagram.
