Rastislav Dvornický: Large deep underwater neutrino telescope in Lake Baikal
The
abstract: the Baikal-GVD is a large neutrino telescope under
construction in Lake Baikal. Recently it is the largest neutrino
telescope operating in Northern Hemisphere. The winter expedition of
2023 results in the three-dimensional detector array of 3 456
photo-sensitive units (optical modules). The data collection is allowed
by the design of the experiment while being in a construction phase. In
this contribution the design and the basic characteristics of the
Baikal-GVD detector are presented.
Eliška Eckerová: Development of the double cascade reconstruction techniques in the Baikal-GVD neutrino telescope
The
abstract: the Baikal-GVD is a neutrino telescope under construction in
Lake Baikal - the deepest freshwater lake in the world. The main aim of
this telescope is to detect astrophysical neutrinos via detection of the
Cherenkov radiation emitted by the products of neutrino interactions.
The basic detection unit of the Baikal-GVD is a photomultilpier tube
enclosed in the pressure resistant glass sphere called optical module.
In 2023, the Baikal-GVD consists of 3456 optical modules. One of the
methods for observation of astrophysical neutrinos is detection of
high-energy tau neutrinos, since their production rate in the atmosphere
is negligible. If tau lepton originating in the charged current
interaction of tau neutrino decays into electron or hadrons, so called
double cascade signature is created. In this contribution development of
the double cascade reconstruction techniques will be presented.
Zuzana Bradáčová: Selection techniques of neutrino-induced cascade events in the Baikal-GVD neutrino telescope
The
abstract: he Baikal Gigaton Volume Detector (Baikal-GVD) is a
3-dimensional array of optical modules immersed to a depth of 1366
metres in Lake Baikal, Siberia. Its design is optimized to search for
high-energy neutrinos coming from Galactic and extragalactic sources.
Optical modules detect flashes of Cherenkov light from secondary charged
particles induced in interactions of neutrinos with matter. Some
charged and neutral current neutrino interactions lead to hadronic or
electromagnetic cascade events. Apart from the neutrino cascades, the
cascade-like Cherenkov light topologies can be also induced along the
muon tracks. These event signatures, referred to as background cascades,
constitute the main background in neutrino cascade channel. In this
contribution a developed algorithm for suppression of the background
cascades.
