It has long been conjectured that strong interactions give rise to a Hagedorn spectrum and theoretical arguments have been presented in support of Hagedorn spectrum in large Nc QCD. This paper discusses the extent to which the meson spectrum should be viewed as evidence for a Hagedorn spectrum and argues that data do not provide a strong evidence for the Hagedorn conjecture. The conclusion is based on three reasons. It is shown that ‘realistic’ quark models have a spectrum in which the number… 
Adiabatic Chemical Freeze-out and Wide Resonance Modification in a Thermal Medium
Here we develop a model equation of state which successfully parameterizes the thermodynamic functions of hadron resonance gas model at chemical freeze-out and which allows us to naturally explain
Melting hadrons, boiling quarks
Abstract.In the context of the Hagedorn temperature half-centenary I describe our understanding of the hot phases of hadronic matter both below and above the Hagedorn temperature. The first part of
Towards the glueball spectrum from unquenched lattice QCD
A bstractWe use a variational technique to study heavy glueballs on gauge configurations generated with 2+1 flavours of ASQTAD improved staggered fermions. The variational technique includes glueball
Quantum and stringy corrections to the equation of state of holographic QCD matter and the nature of the chiral transition
We consider the finite temperature phase diagram of holographic QCD in the Veneziano limit (${N}_{c}\ensuremath{\rightarrow}\ensuremath{\infty}$, ${N}_{f}\ensuremath{\rightarrow}\ensuremath{\infty}$
On the Hadronic Mass Spectrum: 2014
The understanding of Hagedorn’s pivotal discovery, the exponential mass spectrum, evolved rapidly. Some of the insights have since been lost from view—I recall the relevance of the preexponential
Entropy production during hadronization of a quark-gluon plasma
Abstract.We revisit some physical pictures for the hadronization of quark-gluon plasma, concentrating on the problem of entropy production during processes where the number of degrees of freedom is


A relativistic quark model for mesons with an instanton-induced interaction
Abstract:We present new results of a relativistic quark model based on the Bethe-Salpeter equation in its instantaneous approximation. Assuming a linearly rising confinement potential with an
Update of the Hagedorn mass spectrum
We present an update of the Hagedorn hypothesis of the exponential growth of the number of hadronic resonances with mass. We use the newest available experimental data for the nonstrange mesons and
Conformal invariance and degrees of freedom in the QCD string.
It is demonstrated that the Hagedorn-like growth of the number of observed meson states can be used to constrain the degrees of freedom of the underlying effective QCD string, and suggests that conformal invariance and modular invariance are indeed reflected in the hadronic spectrum.
Thermodynamics of the QCD plasma and the large-N limit.
The results for SU(N) Yang-Mills theories with N=3, 4, 5, 6, and 8 colors show a very mild dependence on N, supporting the idea that the QCD plasma could be described by models based on the large-N limit.
The Hagedorn temperature Revisited
The Hagedorn temperature, TH is determined from the number of hadronic resonances including all mesons and baryons. This leads to a stable result TH = 174 MeV consistent with the critical and the
Hadronic density of states from string theory.
We present an exact calculation of the finite temperature partition function for the hadronic states corresponding to a Penrose-Güven limit of the Maldacena-Nùñez embedding of the N=1 super
Hadronic matter near the boiling point
SummaryHadron collisions above ∼10 GeV/c primary laboratory momentum show an interesting global aspect (i.e. when averaged over all final channels): they can be described as a superposition of a
