Studies of Quantum Mechanical Coherency Effects in Neutrino-Nucleus Elastic Scattering

Not scheduled


Mr Vivek Sharma (Institute of Physics, Academia Sinica, Taipei, Taiwan)


Neutrino-nucleus elastic scattering provides a unique laboratory to study the quantum mechanical coherency effects in electroweak interactions. We present an analytical formulation [1] to quantify the coherency effects, relate this to nuclear form factors and experimental cross-section ratios, and characterize how its energy dependence leads to complementary among measurements at various neutrino sources with different targets. The latest results and prospects of observing this process at the Kuo-Sheng Reactor Neutrino Laboratory with germanium detectors with O(100 eV) threshold [2] will also be presented.
