Abstract

A recent new measurement and re-analysis of past measurements suggested an
improved quenching factor value and uncertainty for CsI[Na]. This implies a
measurement of the COHERENT experiment of coherent elastic neutrino-nucleus
scattering that is closer to the Standard Model prediction and has less
uncertainty. We illustrate the impact of this improvement by revisiting fits to
the Weinberg angle, neutrino magnetic moments, neutron rms and neutrino charge
radii, neutrino non-standard interactions (in particular those relevant for
LMA-Dark) and new scalar as well as vector bosons. Significant improvement is
observed, particularly for those scenarios coherently affecting the electroweak
SM process.
