Evidence for quark-diquark structure of baryons from fluctuations of conserved charges
MichaÅ Marczenko, Krzysztof Redlich
We study fluctuations and correlations of conserved charges in QCD using a string-based description of the hadronic mass spectrum. Mesons and baryons are modeled as open relativist…
Proton-neutron correlations in baryon-number fluctuations near the liquid-gas transition
MichaÅ Marczenko
We study net-baryon number density fluctuations in isospin-symmetric matter near the nuclear liquid-gas phase transition using the parity doublet model. We analyze second-order sus…
String-based model with Hagedorn temperature of MeV describes the spectrum of mesons and glueballs
MichaÅ Marczenko, GyÅzÅ Kovács, Larry McLerran +1
We consider the thermodynamics of a color-confined phase of quantum chromodynamics (QCD) and pure gauge theory within a string-inspired model, corresponding to a physical spatial d…
Hadron resonance gas is not a good model for hadronic matter in a strong magnetic field
Pasi Huovinen, MichaÅ Marczenko, MichaÅ SzymaÅski +4
We study the effect of magnetic field on particle yields and charge fluctuations in hadron resonance gas. We argue that the big changes in the proton yield and baryon number suscep…
Suppression of dynamical momentum-space shell by chiral symmetry
Bikai Gao, MichaÅ Marczenko
We investigate the appearance of quark degrees of freedom in dense isospin-symmetric nuclear matter. We employ the parity doublet model to incorporate chiral dynamics. Specifically…
Challenges in locating the QCD critical point via constant entropy density contours
MichaÅ Marczenko, MichaÅ SzymaÅski, GyÅzÅ Kovács
A new method was proposed recently to investigate the location of the putative critical point of strongly interacting matter, governed by quantum chromodynamics. By approximating c…
