Search for relativistic magnetic monopoles with the Baikal neutrino telescope NT200

TL;DR

This paper reports on a search for relativistic magnetic monopoles using the Baikal NT200 neutrino telescope, setting flux limits based on Cherenkov radiation observed over nearly three years.

Contribution

It provides the first flux limit on relativistic magnetic monopoles from the Baikal NT200 detector, utilizing Cherenkov radiation detection techniques.

Findings

Set an upper limit on monopole flux

Demonstrated the detector's capability for monopole searches

Contributed to magnetic monopole astrophysics constraints

Abstract

We present a limit on the flux of relativistic monopoles obtained during 994 days of operation of the Baikal neutrino telescope NT200. The search for relativistic monopoles is based on the enormous amount of Cherenkov radiation emitted by these particles.
