摘    要：In this talk, we explore electroweak form factors within the Bogomolnyi-Prasad-Sommerfield (BPS) Skyrme model, using a semi-classical quantization framework. We compute both electromagnetic and neutral current form factors for heavy nuclei, finding good agreement with experimental data, particularly at low momentum transfer. Additionally, an analytic expression for the neutral current form factor for generic nuclei is also derived, expressed as a power series in the momentum transfer. These results are particularly relevant for coherent elastic neutrino-nucleus scattering (CEvNS), where an accurate description of nuclear structure is essential. More generally, this approach provides an alternative to standard phenomenological models and is especially useful for precision neutrino experiments aiming to control theoretical uncertainties in searches for physics beyond the Standard Model.
