The Likelihood of Dcc Formation
We estimate the probability that a disoriented chiral condensate forms during the spherical expansion of a hot medium described by the linear sigma model.

15 صفحه اولOn the Microscopic Dynamics of Dcc Formation
The dynamics of the pion field after a quench is studied in the framework of the linear sigma model. Our aim is to determine to what extent the amplified pion field resembles the DCC picture originally proposed in the early ’90s. We present the result of a computer experiment where, among other things, we study in detail the correlation between isospin orientations of the distinct modes of the ...
متن کاملExperimental Signatures of Anomaly Induced DCC Formation
We discuss possible experimental signatures related to the formation of domains of disoriented chiral condensate (DCC) triggered by the axial anomaly in relativistic heavy ion collisions. Our predictions make use of the feature of the anomaly effect that is coherent over a large region of space, but opposite in sign above and below the ion scattering plane. We predict an enhancement of the frac...
متن کاملDissipation, noise and DCC domain formation
The possibility of forming disoriented chiral condensate (DCC) in relativistic heavy ion collisions has generated considerable research activities in recent years. The idea was first proposed by Rajagopal and Wilczek [1–4]. They argued that for a second order chiral phase transition, the chiral condensate can become temporarily disoriented in the nonequilibrium conditions encountered in heavy i...
