There are expectations for achieving new measurements of the coherent elastic neutrino-nucleus scattering (CENNS) by
using electron antineutrinos from reactor experiments and through muon (electron) neutrinos from spallation neutrino
sources (SNS). The first scenario takes into account very low energy neutrinos while the second one includes
relatively higher energy neutrinos. These measurements would allow improve our knowledge about standard and beyond
Standard Model physics, for instance as regards the nuclear radius and nonstandard interactions, respectively. In
this talk we will show constraints on the neutron radius and nonstandard parameters obtained from CENNS processes in
experiments of both reactor neutrinos and SNS. We will also display that a combination of several experiments could
give rise to more robust constraints on the parameters mentioned above.
