Description
Neutrino Oscillation Physics
The Daya Bay Reactor Neutrino Experiment has accumulated the largest sample of reactor antineutrino interactions to date and will continue operating until the end of 2020. The experiment consists of eight identically designed antineutrino detectors placed underground at different baselines from six 2.9 GWth nuclear reactors. In this talk I will give an overview of our recent results, including...
The neutrino oscillation is the first observed phenomenon beyond the standard model, which can be interpreted in the framework of three neutrino mixings. It is governed by three mixing angles, two mass-squared differences, and one Dirac CP violation phase. The neutrino mass ordering, CP violation phase and the octant of $\theta_{23}$ remain unknown and could be measured by next-generation...
In the Mediterranean Sea there are two neutrino telescopes: ANTARES, currently the largest one, has been operating for more than 10 years. ANTARES provides unprecedented sensitivity for neutrino source searches in the Southern Sky at TeV energies, so that valuable constraints can be set on the origin of the cosmic neutrinos discovered by the IceCube detector. ANTARES has also constrained the...
The IceCube Neutrino Observatory is a cubic-km size detector consisting
of 5000 light sensors buried within the ice of the South Pole. Together
with its inner array DeepCore (which has a lower energy threshold of ~
5GeV), IceCube detects neutrinos of all flavours by recording the
Cherenkov light emitted by both neutral and charged current interactions
within the ice. Given its ~GigaTon...
By formulating a new perturbative framework we try to reveal characteristic
features of neutrino oscillation which are relevant for possible precision measurement of mixing parameters. Most notably, we show that the effect of CP phase is larger by a factor of ~10 compared to conventional LBL experiments such as T2HK and DUNE. I also mention possible ways for improving uncertainty of...
NOvA is a world-leading long-baseline neutrino oscillation experiment. It uses the 700 kW NuMI beam at Fermilab to send muon neutrinos to two functionally identical detectors, located slightly off the beam axis. The Near Detector is located underground in Fermilab, while the much bigger 14 kton Far Detector sits on the surface, 810 km further away, in Minnesota. They share the same...
T2K is a long baseline neutrino experiment producing a beam of muon neutrinos at the Japan Particle Accelerator Research Centre on the East coast of Japan and measuring their oscillated state 295 km away at the Super Kamiokande detector. Since 2016 T2K has doubled its data in both neutrino and antineutrino beam modes. Coupled with improvements in analysis techniques this has enabled the...
In this talk I will discuss the capability of the ESS$\nu$SB experiment to measure leptonic CP phase $\delta_{CP}$. In particular I will discuss, (i) sensitivity for different baseline options, (ii) the effect of systematic errors and (iii) optimisation of the neutrino to antineutrino run ratio. In addition I will also present a comparative analysis between T2HK and ESS$\nu$SB, pointing out...
Hyper-Kamiokande (Hyper-K) is a next generation underground water Cherenkov neutrino detector. It will serve as a far detector for a long baseline neutrino oscillation experiment using the J-PARC neutrino beam, with sensitivity to exclude CP conservation over a range of parameter space. Hyper-K has a broad physics program, with further sensitivity to proton decay, atmospheric neutrinos, and...
The European Spallation Source Neutrino Super Beam (ESSnuSB) project aims at a discovery of leptonic CP violation with a precise measurement of the CP phase angle. ESSnuSB is characterized by an intense neutrino beam to be produced at the ESS by a 5-MW proton beam, and the placement of the far detector at the second oscillation maximum.
Preliminary performance assessments of different...
