Sensitivity of Baikal-GVD neutrino telescope to neutrino emission toward the center of Galactic dark matter halo

TL;DR

This paper evaluates the Baikal-GVD neutrino telescope's ability to detect neutrinos from dark matter interactions in the Galactic Center, providing bounds on dark matter properties based on potential signals.

Contribution

It presents the first sensitivity analysis of Baikal-GVD for dark matter signals from the Galactic Center, estimating bounds on dark matter annihilation cross section and lifetime.

Findings

Estimated bounds on dark matter annihilation cross section.

Estimated bounds on dark matter decay lifetime.

Sensitivity levels for various annihilation/decay channels.

Abstract

We analyse sensitivity of the gigaton volume telescope Baikal-GVD for detection of neutrino signal from dark matter annihilations or decays in the Galactic Center. Expected bounds on dark matter annihilation cross section and its lifetime are found for several annihilation/decay channels.
