Abstract
Carpet-2
is an air-shower array at Baksan Valley, Russia, equipped with a
large-area (175 m2) 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 Eγ>1 PeV, directionally
associated with IceCube high-energy neutrino events, in the data obtained
in 3080 days of Carpet-2 live time.
