“…Thus possible macrofluctuations in any tank were not seen by experimental monitoring of a single muon rate from upper hemisphere [30,31], while a tiny effect were observed due to enough level of stability in the settings of the Baksan multiyears measurements. It was shown [55] the season variations in observed rate of downgoing muons with magnitude value about 1% over all visible part of the sky. As known, these variations arise from changes of stratosphere temperature.…”

We present a new dataset analysis of the neutrino experiment at the Baksan Underground Scintillator Telescope with muon energy threshold about 1 GeV for the longest exposure time toward the Sun. In search for a signal from self-annihilations of dark matter particles in the center of the Sun we use an updated sample of upward through-going muons for 24.12 years of live time. No observable excess has been found in measured muons relative to expected background from neutrinos of atmospheric origin. We present an improved data analysis procedure and describe it in detail. We set the 90% C.L. new upper limits on expected neutrino and muon fluxes from dark matter annihilations in the Sun, on the corresponding annihilation rates and cross sections of their elastic scattering off proton.Keywords: high energy neutrinos, dark matter. †Dedicated to the memory of Stas Mikheyev.
