BaikalGVD: The First Reconstructed Neutrino-Induced Cascade Interactions

Lukáš Fajt

Institute of Experimental and Applied Physics, CTU in Prague

Abstrakt:

The installation of the neutrino telescope Baikal-GVD started in 2015 and recently, more than half of its final sensitive volume, 0.4 km3, is already instrumented by 1440 light sensitive optical modules. Their only goal, in the darkness of approximate 1 km depth of Lake Baikal, is the detection of Cherenkov light produced by the ultra relativistic secondary charged particles created in the interactions of high energy neutrinos. Neutrinos that are coming from unimaginable distances accelerated to the energies unreachable by the humankind in the processes on the edge of our understanding billions years ago.

In this talk, the brief description of the neutrino astronomy, of the neutrino telescope BaikalGVD and of the high energy neutrino detection mechanisms is going to be given. In addition, the most recent results achieved in the data analysis are going to be presented with emphasis to the newly implemented neutrino-induced cascade interaction reconstruction. The reconstruction algorithm, achieved positional and angular precision and the first reconstructed cascades are going to be introduced. The presentation is going to be accompanied by a short video from the winter expedition at the lake where the new parts of the detector are installed.
