Query: About the possible signature of pion bose condensation contribution in
  the high energy cosmic ray nuclear interactions   The events of anomalous energy deposit and high number of hadrons in hadron
calorimeter, often not accompanied at all, or accompanied by very small EAS of
cosmic rays, are observed by means of the complex installation aimed at
research of cosmic rays. The data quoted and their analysis point to the real
contribution and the essential role of pion Bose condensation in high energy
nuclear interactions. The possibility of the existence of such process in the
nuclear matter (in the neutron stars and in some kinds of the nuclei) was
proposed by A.B.Migdal in 1971.
