We classify new physics signals in coherent elastic neutrino-nucleus\nscattering (CE\νNS) processes induced by 8B solar neutrinos in multi-ton\nxenon dark matter (DM) detectors. Our analysis focuses on vector and scalar\ninteractions in the effective and light mediator limits after considering the\nconstraints emerging from the recent COHERENT data and neutrino masses. In both\ncases we identify a region where measurements of the event spectrum alone\nsuffice to establish whether the new physics signal is related with vector or\nscalar couplings. We identify as well a region where measurements of the recoil\nspectrum are required so to establish the nature of the new interaction, and\ncategorize the spectral features that enable distinguishing the vector from the\nscalar case. We demonstrate that measurements of the isospin nature of the new\ninteraction and thereby removal of isospin related degeneracies are possible by\ncombining independent measurements from two different detectors. We also\ncomment on the status of searches for vector and scalar interactions for\non-going multi-ton year xenon experiments.\n
