Current status and projected sensitivity of COSINE-100

TL;DR

COSINE-100 is a direct detection experiment using NaI(Tl) crystals aiming to independently verify the DAMA claim of WIMP dark matter detection, with current status and future sensitivity projections.

Contribution

This paper reports the current status and projected sensitivity of COSINE-100 and COSINE-200 in testing the DAMA dark matter claim using identical target material.

Findings

COSINE-100 is operational with 106 kg of NaI(Tl) crystals.

Projected sensitivities indicate potential to confirm or refute DAMA's claim.

The experiment aims to resolve the tension in WIMP dark matter detection results.

Abstract

COSINE-100, a direct detection WIMP dark matter search, is using 106 kg of NaI(Tl) crystals to definitively test the DAMA collaboration's claim of WIMP discovery. In the context of most standard models of WIMP dark matter, the DAMA result is in conflict with other direct detection experiments. To resolve this tension, COSINE-100 seeks to independently test the DAMA observation using a detector of the same target material as DAMA, thus definitively confirming or refuting their claim of WIMP discovery. Here, we present the current status and projected sensitivity of COSINE-100, along with the projected sensitivity of COSINE-200, a possible next phase of the experiment.
