Abstract

The article considers events recorded in an experiment with X-ray emulsion chambers (XREC) to study the trunks of extensive air showers (EAS) with energies of nuclei of primary cosmic radiation (PCR) E0 > 100 TeV, which currently have no explanation within the standard model of nuclear interactions (SM). The XREC method is the only one that allows studying EAS trunks with a high coordinate resolution of about 100 microns. EAS trunks contain the most complete information about primary acts of nuclear interactions, as a result of which all unusual events recorded by the XREC method are of great scientific interest. Several types of unusual events recorded by the XREC method were explained within the SM.
