چکیده

We discuss the eeect of strong electromagnetic elds on chiral orientation in the framework of the linear model. Based on lessons we learn from computation of the eeective potential at one loop, we argue that the chiral U(1) anomaly dominates chiral disorientation driven by electromagnetism. We show that the anomaly eeect induces a quasi-instantaneous \kick" to eld conngurations along the 0 direction in relativistic heavy ion collisions. We discuss the possibility that a \kick", even though small in magnitude, can have a substantial eeect on the formation of chirally misaligned domains.

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. Typeset using REVTEX 1 There has been much interest recently in the possible production of a disoriented chiral condensate in high energy hadronic or heav...

Out-of-equilibrium Photon Production from Disoriented Chiral Condensates

We study the production of photons through the non-equilibrium relaxation of a disoriented chiral condensate. We propose that to search for nonequilibrium photons in the direct photon measurements of heavy-ion collisions can be a potential test of the formation of disoriented chiral condensates.

Enhancement of disoriented chiral condensate domains with friction

We investigate the effect of friction on domain formation in disoriented chiral condensate. Including a friction term, we solve the equation of motion of the linear sigma model fields, in the Hartree approximation. With boostinvariance and cylinderical symmetry, irrespective of friction, on average, we donot find any indication of domain like formation with quenched initial condition. However, ...

Signals of Disoriented Chiral

If a disoriented chiral condensate is created over an extended space-time region following a rapid cooling in hadronic or nuclear collisions, the misalign-ment of the condensate with the electroweak symmetry breaking can generate observable effects in the processes which involve both strong and electromagnetic interactions. We point out the relevance of the dilepton decay of light vector mesons...
