Thermal Fluctuations of Disoriented Chiral Condensate Domains
نویسندگان
چکیده
We argue that disoriented chiral condensate (DCC) domains are not well defined for temperatures above the Ginzburg temperature TG (≃ 0.7Tc). Above TG, the dynamics of DCC domains is dominated by thermal fluctuations leading to fluctuating orientation of the chiral field in a given domain. It implies that DCC domains may form even in relatively lower energy collisions where the temperature only reaches TG, and never rises to Tc. It also means that detection of DCC can not be taken as a signal for an intermediate chirally symmetric phase of matter. Using these considerations, we estimate the probability distribution for DCC domains as a function of the chiral angle. PACS numbers: 25.75.Gz, 12.38.Mh, 12.39.Fe

Dissipation, 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...

The probability distribution of neutral pion fraction from independent domains of disoriented chiral condensate is characterized. The signal for the condensate is clear for a small number of domains but is greatly reduced for more than three.

متن کاملQuantum phenomenology for the disoriented chiral condensate.
We consider the quantum state describing the Disoriented Chiral Condensate (DCC), which may be produced in high energy collisions. We show how a mean field treatment of the quantum equations corresponding to the classical linear sigma model leads to a squeezed state description of the pions emerging from the DCC. We examine various squeezed and coherent state descriptions of those pions with pa...
