Abstract We quantify the effects of light spin-zero particles with pseudoscalar couplings to leptons and scalar couplings to nucleons on the evolution of solar neutrinos. In this scenario the matter potential sourced by the nucleons in the Sun’s ma

Abstract We determine the solar neutrino fluxes from the global analysis of the most up-to-date terrestrial and solar neutrino data including the final results of the three phases of Borexino. The analysis are performed in the framework of three-neut

Abstract We derive new constraints on effective four-fermion neutrino non-standard interactions with both quarks and electrons. This is done through the global analysis of neutrino oscillation data and measurements of coherent elastic neutrino-nucleu

In the 3-3-1 model with right-handed neutrinos (331RHNs), three triplets of scalars engender the correct sequence of symmetry breaking, SU(3)C×SU(3)L×U(1)X→SU(3)C×SU(2)L×U(1)Y→SU(3)C×U(1)EM, generating mass for all fermions, except neutrinos

Abstract We present a detailed analysis of the spectral data of Borexino Phase II, with the aim of exploiting its full potential to constrain scenarios beyond the Standard Model. In particular, we quantify the constraints imposed on neutrino magnetic

The minimal scalar sector of the 3-3-1 model is composed by the SU(3)L triplet scalars η, ρ, χ and its potential allows the trilinear term f2χηρ. Since f is an energy scale associated to the explicit violation of Peccei-Quinn global symmetry, i

Since the heavy neutrinos of the inverse seesaw mechanism mix largely with the standard ones, the charged currents formed with them and the muons have the potential of generating robust and positive contribution to the anomalous magnetic moment of th
