Neutrino physics with the Baksan Underground Scintillation Telescope
The neutrino experiment at the Baksan Underground Scintillation Telescope is operating for 35 years. We present an updated analysis of observed upward through-going muons in searches for a signal from dark matter annihilations in the Sun and the astrophysical local sources
Annihilation of NMSSM neutralinos in the Sun and neutrino telescope limits
We investigate neutralino dark matter in the framework of NMSSM performing a
scan over its parameter space and calculating neutralino capture and
annihilation rates in the Sun. We discuss the prospects of searches for
neutralino dark matter in neutrino experiments depending on neutralino content
and its main annihilation channel. We recalculate the upper limits on
neutralino-proton elastic cross sections directly from neutrino telescopes
upper bounds on annihilation rates in the Sun. This procedure has advantages as
compared with corresponding recalcalations from the limits on muon flux,
namely, it is independent on details of the experiment and the recalculation
coefficients are universal for any kind of WIMP dark matter models. We derive
90% c.l. upper limits on neutralino-proton cross sections from the results of
the Baksan Underground Scintillator Telescope.Comment: 28 pages, 16 figures, accepted for publication in JCAP, references

Indirect Neutralino Detection Rates in Neutrino Telescopes
Neutralinos annihilating in the center of the Sun or the Earth may give rise
to a detectable signal of neutrinos. We derive the indirect detection rates for
neutrino telescopes in the minimal supersymmetric extension of the standard
model. We show that even after imposing all phenomenological and experimental
constraints that make the theories viable, regions of parameter space exist
which can already be probed by existing neutrino telescopes. We compare with
the discovery potential of supersymmetry at LEP2 as well as direct detections
and point out the complementarity of the methods.Comment: LaTeX, 18 pages with 9 eps-figure
