A full Monte-Carlo simulation of Centauro-like events is carried out using a model where these events are a result of isotropic decaying of "exotic fireballs" coherently produced in diffractive dissociation. The input testaments to the event generator are explained in detail and we find that the model predictions are in agreement with available data from emulsion chamber experiments. Centauro-type events a t collider experiments are also reexamined and discussed within this context. We show that, at the extremely high energy region Eo > l o 5 TeV, an exotic dominant channel is consistent with experimental data. PACS number(s): 96.40.De, 1 3 . 8 5 . T~

Presented in this study is a possible coherent emission of pions from a large domain of disoriented chiral condensate ͑DCC͒ in the leading particle region, through their influence on the development of the ␥-hadron families, initiated by cosmic ray particles in the atmosphere. The production rate of DCC's is obtained by using a phenomenological framework in the quenching approximation and is included in a Monte Carlo code. In this context, we have found, under the assumption of a ''normal'' proton dominant composition in the primary flux, that the anomalous hadron-rich families, observed in the experimental data, can be reproduced. However, the production rate of DCC's obtained here is not enough to describe the global characteristics, such as the family flux, observed at mountain altitudes. The implications of these results are here discussed.
