Abstract: We have found by using robust observables in experimental cosmic ray gamma-hadron families (100 TeV < Evis < 700 TeV) detected at mountain altitudes that there are peculiar clusters with large asymmetries in the neutral pion fraction distribution, absent in the artificial generic families. A qualitative explanation of this result can be associated to copious production of pions in the far-forward angular region from a channel of DCC generation in nuclear collisions.
