Abstract
ANTARES is an underwater neutrino detector in the Mediterranean Sea. Due to its location, its reconstruction accuracy for all-flavor neutrino interactions, and its low energy threshold for neutrino detection, the ANTARES observatory best performs in searches for neutrinos below 100 TeV over large parts of the sky. The HAWC experiment is a water Cherenkov gamma-ray detector located in Mexico. Thanks to its large field of view it is an excellent instrument to observes the very-high energy gamma-ray sky and perform high-sensitivity surveys of the Galactic Plane. The 10 year ANTARES data set and 3 years of HAWC point source surveys are used to search for all- flavor neutrino emission in correlation with the highly-significant observations by HAWC in the gamma-ray sky by means of a maximum-likelihood template search. No significant observation for a correlation has been identified and upper limits on the neutrino flux from the HAWC observations have been set.
