Search for Neutrinos from the Core of the Earth with the Baikal Underwater Detector NT-36

The first stage of the Baikal Neutrino Telescope NT-200, the detector NT-36, was operated from 1993 to 95. The data obtained with this small array were analysed to search for vertically upward muons. Apart from neutrinos generated in the atmosphere at the opposite side of the Earth, such muons might be due to neutrinos produced in neutralino annihilations in the center of the Earth. We have selected two clear neutrino candidates. From this, an 90%CL upper limit of 1.3 x 10^-13 muons cm^(-2) sec^(-1) in a cone with 15 degree half-aperture around the opposite zenith is obtained for muons due to neutralino annihilation.

Preliminary Results on a Search for Neutrinos from the Center of the Earth with the Baikal Underwater Telescope

The deep underwater Cherenkov neutrino telescope NT-200 is currently under construction at lake Baikal. Its first stage NT-36 consisting of 36 optical modules has operated over 2 years since April 1993 till March 1995. Here we present a method to search for nearly vertical upward going muons from neutralino annihilation in the center of the Earth. We present preliminary results obtained from experimental data taken with the NT-36 array in 1994.

The Baikal Experiment: Status Report

We review the present status of the Baikal Neutrino Project. The construction and performance of the large deep underwater Cherenkov detector for muons and neutrinos, NT-200, which is currently under construction in Lake Baikal are described. Some results obtained with the first stages of NT-200 - NT-36 (1993-95), NT-72 (1995-96) and NT-96 (1996-97) - are presented, including the first clear neutrino candidates selected with 1994 and 1996 data.

The Baikal Deep Underwater Neutrino Experiment Status Report

We review the present status of the Baikal Deep Underwater Neutrino Experiment. The construction and performance of the large deep underwater Cherenkov detector for muons and neutrinos, NT-200 (Neutrino Telescope with 200 phototubes), which is currently under construction in Lake Baikal are described. Some results obtained with the intermediate detectors NT-36 (1993-95), NT-72 (1995-96) and NT-96 (1996-97) are presented, including the first clear neutrino candidates selected with 1994 and 1996 data.

Reconstruction of Atmospheric Neutrinos with the Baikal Neutrino Telescope NT-96

We describe the track reconstruction procedure for events recorded with the Neutrino Telescope NT-96. After having identified 2 neutrino candidates close to the opposite zenith with the small prototype telescope NT-36, we present here results of the reconstruction of 5.3 x 10^6 muons, recorded with NT-96 during its first 18 days lifetime. We have separated 3 neutrino candidates, compared to 2.3 events expected from MC calculations.
