Query: Looking for the possible gluon condensation signature in sub-TeV
  gamma-ray spectra: from active galactic nuclei to gamma ray bursts   The gluon condensation in the proton as a dynamical model is used to treat a
series of unsolved puzzles in sub-TeV gamma ray spectra, they include the
broken power-law of blazar's radiation, the hardening confusion of 1ES
1426+428, Mkn 501, and the recently recorded sub-TeV gamma spectra of GRB
180720B and GRB 190114C. We find that the above anomalous phenomena in gamma
ray energy spectra can be understood with the simple broken power law based on
a QCD gluon condensation effect.
