Comment on "Fitting the annual modulation in DAMA with neutrons from muons and neutrinos''

TL;DR

This paper evaluates whether solar neutrino-induced neutrons could explain DAMA/LIBRA's annual modulation and concludes that such an explanation is unlikely due to the improbably large cross sections required.

Contribution

It provides an estimation showing that neutrino-induced neutron rates are insufficient to account for DAMA's observed modulation, challenging previous hypotheses.

Findings

Neutrino-induced neutron contribution is negligible in DAMA/LIBRA.

Required cross sections are several orders of magnitude larger than current calculations.

Solar neutrino effects are unlikely to explain DAMA's annual modulation.

Abstract

We estimate rates of solar neutrino-induced neutrons in a DAMA/LIBRA-like detector setup, and find that the needed contribution to explain the annual modulation would require neutrino-induced neutron cross sections several orders of magnitude larger than current calculations indicate. Although these cross sections have never been measured, it is likely that the solar-neutrino effect on DAMA/LIBRA is negligible.
