Title: CEvNS with RED-100 detector

Abstract: The Coherent elastic neutrino-nucleus scattering (CEvNS) was predicted long ago, but observed only recently. This process is cleanly predicted in the Standard Model and its measurement provides a Standard Model test. This process is involved in supernova explosion processes and supernova neutrino detection. It also represents a background floor for dark matter direct detection and is interesting as a method of nuclear reactor monitoring for non-proliferation. A brief description for the process is presented. Many experiments are running now to study this phenomena. The short introduction to the most promising ones is provided. Among those is the RED-100: a two-phase emission detector created to investigate CEvNS off xenon nuclei. Its active volume has a cylindrical shape with sizes of ~ 40 cm. The total mass of liquid xenon in the detector equals 200 kg. The detector performance provides sensitivity down to a single ionization electron, while allows operation at a ground surface environment. In this talk, the current status of the RED-100 detector is presented. The plan of the experiment at Kalinin Nuclear Power Plant is given.
