Description

Neutrino nucleus elastic scattering ($\nu A_{el}$) is an electroweak interaction of the Standard Model of particle physics. We formulate a quantitative and universal parametrization of the quantum mechanical coherency effects in $\nu A_{el}$ [1], under which the experimentally accessible misalignment phase angle between nonidentical nucleonic scattering centers can be studied. We relate it to the conventional description of nuclear many-body physics through form factor and data-driven cross section reduction fraction [2]. Limits on the latest CsI and LAr data from COHERENT collaboration along with prospects of observing the $\nu A_{el}$ process at the Kuo-Sheng Reactor Neutrino Laboratory with Germanium detectors with ${O}$(100 eV) threshold will also be presented.
