Abstract: | Experimental data obtained with the aid of the Baksan underground scintillation telescope over a long period of its operation
are analyzed with the aim of searches for an excess flux of ultrahigh-energy (≥100 TeV)muons. The multiple-interaction method,
which is based on the ideas of the pair-meter technique, is used to analyze the energy spectrum of the muons. The phenomenological
parameters of this method and its sensitivity to the shape of the spectrum are discussed. The experimental distributions are
compared with the results of calculations for various versions of the muon spectrum. The possibility of separating ultrahigh-energy
muons that fly in the vicinity of the axis of extensive air showers is assessed on the basis of the integrated number of recorded
and simulated events featuring large energy depositions. |
