Colloquium Towards CP violation in neutrino Physics

The aim of the Colloquium is to present a status and plans for CP violation measurement in neutrino experiments.  It plans to provide an overview of recent experimental results, theoretical predictions, experiments under construction and planned experiments to measure CP violation in lepton sector.
It consists of invited talks.

09:05 → 09:35 Latest Results From Daya Bay

The Daya Bay Reactor Neutrino Experiment is designed to provide a precise measurement of the smallest neutrino-mixing angle, θ13. It is located at the Daya Bay Nuclear Power Complex in southern China. Eight antineutrino detectors with identical design, each with a 20-t gadolinium-doped liquid-scintillator target, are deployed in three underground experimental halls at different distances from six nuclear reactors for detecting the low-energy electron antineutrinos emitted from the cores. Mixing angles and mass-squared differences are determined by comparing the observed rates and spectra of antineutrinos in the far detectors with the predicted one based on the corresponding measurements obtained from the near detectors. This kind of relative measurement can reduce systematic uncertainties significantly. Using this approach, Daya Bay provides precise determination of θ13 and |Δm232|. With a few million reactor antineutrino events collected, Daya Bay can also perform other precision measurements and sensitive searches. Some of the recent results and prospects of Daya Bay will be presented in this talk.

10:00 → 10:30 Status and perspectives of the JUNO experiment

JUNO (Jiangmen Underground Neutrino Observatory), a 20 kton multi-purpose underground liquid scintillator detector, has been proposed and approved for realization in the south of China. After an intense design phase, the overall structure of the detector has been fully finalized, paving the way towards the construction of the several components and subsystems, which is now in a very advanced stage. Meanwhile, the excavation of the site, which will host the experiment is rapidly progressing towards its completion. The main physics target of JUNO is the determination of the neutrino mass hierarchy, which will be accessible through the measurement of the antineutrino spectrum from two high power nuclear complexes under installation 53 km away from the experimental site. In my talk I will describe the broad physics capabilities of the experiment, which include in addition to the crucial measure of the neutrino hierarchy the high precision determination of three oscillation parameters, as well as a rich astroparticle program. Moreover, I will illustrate the main technical characteristics of the detector, and I will report the status of the construction work.

Neutrino activities at CERN have strongly developed in recent years, following the recommendation of the European Strategy Group issued in 2013: “to pave the way to the for a substantial European role in future long-baseline experiments”. A large facility for R&D and test of neutrino detectors has grown. The main programmes will be discussed, including the prototypes of the DUNE long-baseline project, contributions to the Short Base-line Neutrino project at FNAL and to the Near Detector upgrade for T2K. Physics studies currently taking place will also be illustrated.

17:00 → 17:30 Status of the DANSS project

The DANSS is a highly segmented m3 antineutrino-spectrometer aimed to search for SBL sterile neutrino oscillations in reactor sector, as well as to solve applied tasks of monitoring the power and fuel composition of a nuclear reactor. The detector measures the antineutrino spectrum by the IBD method from an industrial nuclear reactor (3.1 GWth, KNNP, Rusia) at distances 10.7-12.7 m from the core using a mobile platform. The search for oscillations in sterile neutrino is carried out through the analysis of the bin-per-bin ratios of the positron energy spectra collected at different distances from the reactor. This relative method is free from systematic errors associated with the calculation of the reactor antineutrino spectra and detector efficiency.
The new results of the DANSS experiment are presented here based on more than 2.1 million events collected in 2016-2019 (2.4-fold increase over published data. With the current full data set we do not have a statistically significant sign of the sterile neutrino oscillations excluding further the large and interesting portion of the 3v+ 1v model phase space. The DANSS’s abilities to measure nuclear fuel composition and to monitor reactor power at high will be also discussed.
