DESCRIPTION:Speakers: Sergey Shaulov (LPI RAS)\nAbstract.\nStudying the sp
 ectrum of secondary particles at the Large Hadron Collider (LHC) at energi
 es equivalent to 1-100 PeV in the laboratory system\, scaling behavior is 
 observed. At the same energies\, a number of effects are observed in cosmi
 c rays (CR) that are incompatible with this behavior. In the spectrum of e
 xtensive  atmospher showers (EAS)\, a break (knee) is observed at an energ
 y of 3 PeV. According to the large ionization calorimeter  at the Tien Sha
 n\, the absorption length of hadron showers increases in the same energy r
 egion. In the hybrid HADRON experiment\, there is a scaling violation in t
 he spectrum of secondary hadrons and an anomalous excess of muons in proto
 n showers. According to the data of X-ray emulsion chambers \, events with
  halos appear in the knee area and effect of alinement in energy centers o
 f gamma-hadron events are observed.. Given the LHC data\, these anomalies 
 should be explained by astrophysical reasons\, i.e. changes in the composi
 tion of cosmic rays.\n\nhttps://indico.nevod.mephi.ru/event/6/contribution
