Isospin Violating Dark Matter Search by Nuclear Emulsion Detector

TL;DR

This paper explores the potential of nuclear emulsion detectors to detect isospin-violating dark matter, which could explain discrepancies in direct detection experiments, leveraging their directional sensitivity and modulation observation capabilities.

Contribution

It assesses the feasibility of future nuclear emulsion detectors to probe favored regions of isospin-violating dark matter parameter space.

Findings

Nuclear emulsion detectors can potentially detect isospin-violating dark matter signals.

Directional sensitivity of the detector allows for modulation property examination.

The study suggests a promising future for nuclear emulsion detectors in dark matter searches.

Abstract

Dark matter signal and its annual modulation of event number are observed by some direct searches in small mass region. However, the regions have been excluded by others. The isospin-violating dark matter is a hopeful candidate to explain the discrepancy. We study the possibility that a future project of dark matter search using nuclear emulsion can reach favored region by the isospin-violating dark matter. Since the detector has the directional sensitivity, it is expected to examine the region including the modulation property.
