Parity doublet model for baryon octets: Ground states saturated by good diquarks and the role of bad diquarks for excited states
Parity doublet model is an effective chiral model that includes the chiral-variant and-invariant
masses of baryons. The chiral-invariant mass has large impacts on the density dependence …

Anatomy of critical fluctuations in hadronic matter
M Marczenko - Physical Review D, 2024 - APS
Critical phenomena in phase transitions of strongly interacting matter, governed by quantum
chromodynamics, are inherently encoded in the fluctuations of conserved charges. In this …
