Localized domains of disoriented chiral condensates

A new method to search for localized domains of disoriented chiral condensa tes (DCC) has been proposed by utilizing the (eta - phi) phase space distri butions of charged particles and photons. Using the discrete wavelet transf ormation (DWT) analysis technique, it has been found that the presence of D CC domains broadens the distribution of wavelet coefficients in comparison to that of normal events. Strength contours have been derived from the diff erences in rms deviations of these distributions by taking into account the size of DCC domains and the probability of DCC production in ultra-relativ istic heavy ion collisions. This technique can be suitably adopted to exper iments measuring multiplicities of charged particles and photons. (C) 1999 Elsevier Science B.V. All rights reserved.
