Parallel talks 6: Neutrino Physics
- Jiangming Yao (Sun Yat-Sen (Zhongshan) University)
The measurement of reactor neutrinos from coherent elastic neutrino-nucleus scattering (CEνNS) experiments can be used to probe quenching factor and new physics. We demonstrate that the constraints to new physics by the recent reactor CEνNS experiment at Dresden-II are quite sensitive to the quenching factor at low recoil energies. We also show that a CEνNS experiment with an ultra-low energy...
Effective field theories (EFTs) have recently undergone rapid developments due to the absence of any new discoveries experimentally. In light of the rich data from various low- and high-energy data now and in the near future, the Standard Model EFT (SMEFT) is adopted as a model-independent tool in searching for new physics indirectly by performing its global fit. While attention has largely...
I will discuss how to analyse neutrino experiments using an Effective Field Theory (EFT) framework. This approach makes possible to include generic non-standard effects in neutrino production and detection, and to study the interplay with non-neutrino experiments. We will discuss the connection with the traditional non-standard interactions (NSI) approach, and the application to specific...
We scrutinize the hypothesis that gauge singlet fermions - sterile neutrinos - interact with Standard Model particles through the transition magnetic moment portal. These interactions lead to the production of sterile neutrinos in supernovae followed by their decay into photons and active neutrinos which can be detected at γ-ray telescopes and neutrino detectors, respectively. We find
that...
Utilizing powerful nuclear reactors as anti-neutrino sources, high mountains to provide ample shielding from cosmic rays in the vicinity, and functionally identical detectors with large target volume for near-far relative measurement, the Daya Bay Reactor Neutrino Experiment has achieved unprecedented precision in measuring the neutrino mixing angle $\theta_{13}$ and the neutrino mass squared...
