Anisotropy in the Directions of Arrival of Muon Bundles Detected at the NEVOD Experimental Complex

Abstract

Results are presented from studying the anisotropy of the flux of very high-energy cosmic rays on the basis of muon bundles. Events were recorded in the period 2012–2018 by the DECOR coordinate-tracking detector, part of the unique research setup of the NEVOD experimental complex. The results from analyzing the anisotropy for two samples of events with muon bundles corresponding to different ranges of primary particle energy (E > 10¹⁵ eV and E > 10¹⁶ eV) are discussed, and estimates are made of dipole anisotropy parameters (amplitude and phase).
