“…The problem is closely related to the fact that a straightforward chiral extension of the Walecka model typically leads to saturation in the restored phase ("Lee-Wick phase" [98]), rather than a phase with broken chiral symmetry. The same happens in the standard NJL model with nucleon degrees of freedom [99,100].…”

The chiral condensate, which is constant in vacuum, may become spatially modulated at moderately high densities where in the traditional picture of the QCD phase diagram a first-order chiral phase transition occurs. We review the current status of this idea, which originally dates back to Migdal's pion condensation, but recently received new momentum through studies on the nature of the chiral critical point and by the conjecture of a quarkyonic-matter phase. We discuss how these nonuniform phases emerge in generalized Ginzburg-Landau analyses as well as in specific calculations, both within effective models and in Dyson-Schwinger or large-N c approaches to QCD. Questions about the most favored shape of the modulations and its dimension, and about the effects of nonzero isospin chemical potential, strange quarks, color superconductivity, and external magnetic fields on these inhomogeneous phases will be addressed as well.

“…Indeed, at the Bear Mountain [127] workshop in Fall 1974 the physics of the forthcoming RHI collisions was discussed in a retreat motivated by Lee-Wick [128] matter, a proposed new state of nuclear matter. These authors claim:…”

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 the review addresses many frequently posed questions about properties of hadronic matter in different phases, phase transition and the exploration of quark-gluon plasma (QGP). The historical context of the discovery of QGP is shown and the role of strangeness and strange antibaryon signature of QGP illustrated. In the second part I discuss the corresponding theoretical ideas and show how experimental results can be used to describe the properties of QGP at hadronization. The material of this review is complemented by two early and unpublished reports containing the prediction of the different forms of hadron matter, and of the formation of QGP in relativistic heavy ion collisions, including the discussion of strangeness, and in particular strange antibaryon signature of QGP.

“…On the other hand, the CMW calculations demonstrate a similar centrality dependency of the slope parameter, though quantitative comparison between data and theory requires further works on both sides to match the kinematic regions of the analyses. The concept of Local Parity (P) Violation (LPV) in high-energy heavy ion collisions was brought up by Lee et al [26,27,28] and elaborated by Kharzeev et al [29]. In non-central collisions such a P-odd domain can manifest itself via preferential same charge particle emission for particles moving along the system's angular momentum, due to the Chiral Magnetic Effect [2,3].…”

We present measurements of pion elliptic flow (v 2 ) in Au+Au collisions at √ s NN = 200, 62.4, 39, 27 and 19.6 GeV, as a function of event-by-event charge asymmetry (A ± ), based on data from the STAR experiment at RHIC. We find that π − (π + ) elliptic flow linearly increases (decreases) with charge asymmetry for most centrality bins and for all the beam energies under study. The slope parameter (r) from v 2 (A ± ) difference between π − and π + shows a centrality dependency similar to calculations of the Chiral Magnetic Wave. The measurements of charge separation with respect to the reaction plane in search of Local Parity Violation and the Chiral Magnetic Effect are also presented for Au+Au collisions at √ s NN =
