Description
Coherent elastic neutrino–nucleus scattering (CEνNS) provides a powerful probe of Standard Model neutral-current interactions, neutrino properties, nuclear structure, and new physics. In this talk, I will present a comprehensive EFT framework for CEνNS that systematically connects high-energy ultraviolet scenarios to low-energy nuclear recoil observables. By incorporating LEFT operators up to dimension 8, QCD renormalization-group running, and chiral matching via the spurion method, we establish a top-down pipeline from tree-level UV completions through SMEFT and LEFT to nuclear response functions and experimental data. Using current CEνNS measurements, this framework enables global constraints on generic EFT coefficients, neutrino non-standard interaction parameters, and underlying UV model parameters, thereby bridging model building, precision neutrino measurements, and low-energy nuclear physics.
