Peculiar seasoning in the neutrino day-night asymmetry: where and when to look for spices?

TL;DR

This paper investigates seasonal variations in solar neutrino day-night asymmetry, especially around winter solstice, highlighting potential detectable effects with future neutrino detectors.

Contribution

It identifies specific seasonal effects linked to the winter solstice that could be observed with upcoming neutrino detection technology.

Findings

Seasonal effects are significant near winter solstice.

Certain detector placements enhance the observability of these effects.

Next-generation detectors may detect these seasonal asymmetries.

Abstract

We analyze the peculiar seasonal effects in the day-night asymmetry of solar neutrinos, namely those connected with the neutrino nighttime flux anomaly near the winter solstice. We show that, for certain placements of the neutrino detector, such effects may be within the reach of next-generation detectors.
