Abstract: We present a systematic study of the large asymmetries in neutral pion fraction distribution in high energy cosmic ray families (100 TeV<E-vis<700 TeV) detected at high mountain altitudes at Pamir (4300 m, 595 g/cm(2)). With this in mind we have constructed robust observables, ratios of factorial moments, in experimental and simulated families in a similar way. We have found that our experimental data do not exclude the possibility of a DCC formation mechanism in high energy interactions. [S0556-2821(99)06901-5].
