A highly successful description of QGP hadronization is based on statistical phase space weighting<ref>{{Cite journal|last1=Rafelski|first1=Johann|last2=Letessier|first2=Jean|year=2003|title=Testing limits of statistical hadronization|url=https://linkinghub.elsevier.com/retrieve/pii/S0375947402014185|journal=Nuclear Physics A|language=en|volume=715|pages=98c–107c|doi=10.1016/S0375-9474(02)01418-5|arxiv=nucl-th/0209084|bibcode=2003NuPhA.715...98R |s2cid=18970526 }}</ref> according to the Fermi–Pomeranchuk model of particle production.<ref>{{Citation|last=Hagedorn|first=Rolf|title=The Long Way to the Statistical Bootstrap Model|url=http://link.springer.com/10.1007/978-1-4615-1945-4_2|work=Hot Hadronic Matter|series=NATO ASI Series |volume=346|pages=13–46|year=1995|editor-last=Letessier|editor-first=Jean|place=Boston, MA|publisher=Springer US|doi=10.1007/978-1-4615-1945-4_2|isbn=978-1-4613-5798-8|access-date=2020-06-25|editor2-last=Gutbrod|editor2-first=Hans H.|editor3-last=Rafelski|editor3-first=Johann|url-access=subscription}}</ref> This approach was developed, since 1950, initially as a qualitative description of strongly interacting particle production. It was originally not meant to be an accurate description, but a phase space estimate of upper limit to particle yield. In the following years numerous hadronic resonances were discovered. [[Rolf Hagedorn]] postulated the statistical bootstrap model (SBM) allowing to describe hadronic interactions in terms of statistical resonance weights and the resonance mass spectrum. This turned the qualitative Fermi–Pomeranchuk model into a precise statistical hadronization model for particle production.<ref>{{Cite journal|last1=Torrieri|first1=G.|last2=Steinke|first2=S.|last3=Broniowski|first3=W.|last4=Florkowski|first4=W.|last5=Letessier|first5=J.|last6=Rafelski|first6=J.|year=2005|title=SHARE: Statistical hadronization with resonances|url=https://linkinghub.elsevier.com/retrieve/pii/S0010465505000755|journal=Computer Physics Communications|language=en|volume=167|issue=3|pages=229–251|doi=10.1016/j.cpc.2005.01.004|arxiv=nucl-th/0404083|bibcode=2005CoPhC.167..229T |s2cid=13525448 }}</ref> However, this property of hadronic interactions poses a challenge for the statistical hadronization model as the yield of particles is sensitive to the unidentified high mass hadron resonance states. The statistical hadronization model was first applied to relativistic heavy-ion collisions in 1991, which led to the recognition of the first strange anti-baryon signature of quark-gluon plasma discovered at [[CERN]].<ref>{{Cite journal|last=Rafelski|first=Johann|year=1991|title=Strange anti-baryons from quark-gluon plasma|url=https://linkinghub.elsevier.com/retrieve/pii/037026939191576H|journal=Physics Letters B|language=en|volume=262|issue=2–3|pages=333–340|doi=10.1016/0370-2693(91)91576-H|bibcode=1991PhLB..262..333R |url-access=subscription}}</ref><ref>{{Cite journal|last1=Abatzis|first1=S.|last2=Barnes|first2=R.P.|last3=Benayoun|first3=M.|last4=Beusch|first4=W.|last5=Bloodworth|first5=I.J.|last6=Bravar|first6=A.|last7=Caponero|first7=M.|last8=Carney|first8=J.N.|last9=Dufey|first9=J.P.|last10=Evans|first10=D.|last11=Fini|first11=R.|year=1990|title=Λ and production in sulphur-tungsten interactions at 200 GeV/c per nucleon|url=https://linkinghub.elsevier.com/retrieve/pii/037026939090282B|journal=Physics Letters B|language=en|volume=244|issue=1|pages=130–134|doi=10.1016/0370-2693(90)90282-B}}</ref>
