Also, any prospective extension of the Standard Model that accommodates small neutrino masses may inherently entail non-standard interactions (NSIs) between neutrinos and matter giving rise to an alternative parameter space (Dark-LMA) that remains compatible with existing neutrino oscillation data. We study possible breaking scenarios of scaling ansatz in light of the large mixing angle (LMA) and Dark-LMA solutions suggested by current neutrino oscillation data.
