abstract = {The Borexino detector measures solar neutrino fluxes via
neutrino-electron elastic scattering. Observed spectra are
determined by the solar-νe survival probability Pee(E), and
the chiral couplings of the neutrino and electron. Some
theories of physics beyond the Standard Model postulate the
existence of Non-Standard Interactions (NSI’s) which
modify the chiral couplings and Pee(E). In this paper, we
search for such NSI’s, in particular, flavor-diagonal
neutral current interactions that modify the νee and ντe
couplings using Borexino Phase II data. Standard Solar Model
predictions of the solar neutrino fluxes for both high- and
low-metallicity assumptions are considered. No indication of
new physics is found at the level of sensitivity of the
detector and constraints on the parameters of the NSI’s
are placed. In addition, with the same dataset the value of
sin2θW is obtained with a precision comparable to that
achieved in reactor antineutrino experiments},
