The most dynamically developing field of particle physics is physics of neutrinos. Neutrinos are so different from other particles, that they are considered probably the most promising clue to physics beyond the Standard model. They are believed to help answering the question of observed matter-antimatter asymmetry in the universe.

One of currently running neutrino experiments is NOvA experiment, located near Chicago and in Minnesota, USA.

Experiment NOvA, Fermilab, USA

Physicists expose its detectors (Near Detector and Far Detector), where Far Detector is the largest plastic structure ever built, to the most powerfull neutrino beam in the world and try to unravel neutrino mysteries, like neutrino mixing parameters, neutrino mass hierarchy or δ_CP parameter describing the difference in neutrino-antineutrino behavior.

Our group is responsible for development, maintenance and upgrade of online DAQ software monitoring the overall health of NOvA detectors and collection of data about data acquisition system problems. Our team members also took part in experimental data analysis, namely neutrino mixing parameters measurement or search for sterile neutrinos.
