Abstract
This work demonstrates that once a large number of pion is condensed in a high-energy hadron collision, the gamma-ray spectrum from decay takes on a typical broken power-law shape, which has been documented in many astronomical observations, but we have not yet recognized it. We show that this pion condensation is caused by a large number of soft gluons condensed in protons.
