Abstract
We describe some detailed numerical simulations of Disoriented Chiral Condensates (DCCs), using the chiral lagrangian as a controlled long-wavelength description. We focus on the possibility of multiple, independently coherent domains, and investigate the degree to which the DCC signal is attenuated. As an intermediate step in our analysis we compute the expected number of detector events in each isospin and momentum channel for a given asymptotic classical field configuration. We find that for sufficiently large initial field strengths, the non-linear interactions between domains become important and can lead to a randomization of isospin orientations. Nevertheless, we argue that viable signals exist for DCC detection, even in the case of multiple domains and strong domain-domain interactions.
