Abstract:
The main purpose of this thesis is to explore the opportunities which would
be provided by the Sieroszowice Underground Laboratory SUNLAB, located in the
Polkowice-Sieroszowice mine in the Lower Silesia province in Poland, to discover
the CP violation in the neutrino sector. This discovery would be a milestone on the
road to understanding the observed dominance of matter over antimatter in the
Universe, which is one of the fundamental questions of contemporary science.The
motivation for the presented study is the current very exciting situation in neutrino
physics. According to many physicists, the discovery of neutrino oscillations in the
years 1998-2002 and their interpretation within the framework of three neutrino
flavour mixing, awarded the 2015 Nobel Prize in physics, provides firm evidence for
new physics beyond the Standard Model. Recently, the θ13 mixing angle has been
determined to be moderately large. This makes it possible to use conventional
high power neutrino beams in accelerator long baseline experiments to answer the
remaining questions in neutrino oscillations, which are the neutrino mass hierarchy
and the measurement of the CP-violating phase.
