Carpet-2 search for PeV gamma rays associated with IceCube high-energy neutrino events
arXiv:1812.02662 · doi:10.1134/S0021364019040015
Abstract
Carpet-2 is an air-shower array at Baksan Valley, Russia, equipped with a large-area (175 m^2) muon detector, which makes it possible to separate primary photons from hadrons. We report the first results of the search for primary photons with energies E_γ>1 PeV, directionally associated with IceCube high-energy neutrino events, in the data obtained in 3080 days of Carpet-2 live time.
