Neutrino oscillation effect on the indirect signal of neutralino dark matter from the Earth core

TL;DR

This paper studies how neutrino oscillations influence the detection signals of neutralino dark matter annihilations in the Earth's core, focusing on muon neutrino flux modifications.

Contribution

It provides a detailed analysis of neutrino oscillation effects on dark matter indirect detection signals considering different oscillation scenarios.

Findings

Neutrino oscillations significantly alter the muon neutrino flux from Earth's core.

Different oscillation channels (nu_mu -> nu_tau and nu_mu -> nu_s) produce distinct effects.

Results help refine dark matter detection strategies considering neutrino physics.

Abstract

We investigate the effect induced by neutrino oscillation on the dark matter indirect detection signal which consists in a muon neutrino flux produced by neutralino annihilation in the Earth core. We consider the neutrino oscillation parameters relevant to the atmosferic neutrino deficit, both in the nu_mu -> nu_tau and nu_mu -> nu_s cases.
