Abstract Although the generation of disoriented chiral condensates (DCCs), where the order parameter for chiral symmetry breaking is misaligned with respect to the vacuum direction in isospin state, is quite natural in the theory of strong interactions, they have so far eluded experiments in accelerators and cosmic rays. If DCCs are formed in high-energy nuclear collisions, the relevant outcome are very large event-by-event fluctuations in the neutral-to-charged pion fraction. In this note we… Expand

We investigate the production of disoriented chiral condensates in ultra high energy collisions and look for an intrinsic signature they could produce in ongoing and future cosmic ray experiments.Expand
How to make large domains of disoriented chiral condensate.
By numerical simulation of the zero-temperature two-flavor linear sigma model, it is found that domains are essentially [ital pion] sized, and it is shown that large domains can occur if the effective mesons masses are much lighter. Expand
Pion production from baked Alaska disoriented chiral condensate
We study the various stages of the evolution of chiral condensates disoriented via the {open_quotes}baked-Alaska{close_quotes} mechanism, in which the condensates are described as the products ofExpand
Hadronic interactions of high energy cosmic-ray observed by emulsion chambers
Abstract Results of cosmic-ray experiments on hadronic interactions are reviewed. Attention is focussed on emulsion chamber experiments which cover the energy region E 0 = 10 13 −10 16 eV, andExpand

Considering a variety of dynamical scenarios within the linear {sigma} model, we examine the conditions for pionic modes to be amplified as the chiral field relaxes towards the normal vacuumExpand
Static and Dynamic Critical Phenomena at a Second Order QCD Phase Transition
In QCD with two flavors of massless quarks, the chiral phase transition is plausibly in the same universality class as the classical four component Heisenberg antiferromagnet. Therefore,Expand
Fast hadronization of supercooled quark-gluon plasma.
A new rapid hadronization scenario is proposed based on the dynamical chiral model including quarks interacting with background meson fields. We estimate time scales and spatial characteristics ofExpand
The Pierre Auger Collaboration
The Pierre Auger Collaboration has reported evidence for anisotropies in the arrival directions of cosmic rays with energies larger thanEth = 55 EeV. There is a correlation above the isotropicExpand
Density inhomogeneities in heavy-ion collisions around the critical point
We study the hydrodynamical expansion of a hot and baryon-dense quark fluid coupled to classical real-time evolution of the long wavelength modes of the chiral field. Significant densityExpand
Cosmic ray event generator Sibyll 2.1
The cosmic ray interaction event generator Sibyll is widely used in extensive air shower simulations. We describe in detail the properties of Sibyll 2.1 and the differences with the original versionExpand
