Backgrounds and Projected Limits from Dark Matter Direct Detection Experiments

TL;DR

This paper introduces a simple formula to estimate how experimental backgrounds can reduce the projected sensitivity of dark matter direct detection experiments.

Contribution

It provides a straightforward method to quantify the impact of backgrounds on experimental projections, aiding in experiment design and analysis.

Findings

The formula accurately predicts background effects on sensitivity.

Backgrounds significantly degrade detection projections.

Useful for planning future dark matter detection experiments.

Abstract
