One needs positive signatures for detection of Dark Matter

TL;DR

This paper emphasizes the importance of detecting annual recoil spectrum modulation as a positive signature for direct dark matter detection, highlighting the need for spectrum measurement to confirm dark matter particles.

Contribution

It underscores the necessity of measuring recoil spectra and annual modulation as key to positive dark matter detection, beyond exclusion limits.

Findings

Annual recoil spectrum modulation is crucial for confirming dark matter.

Measuring recoil spectra is necessary for positive detection.

Focus on spectral measurement enhances detection prospects.

Abstract

One believes there is huge amount of Dark Matter particles in our Galaxy which manifest themselves only gravitationally. There is a big challenge to prove their existence in a laboratory experiment. To this end it is not sufficient to fight only for the best exclusion curve, one has to see an annual recoil spectrum modulation --- the only available positive direct dark matter detection signature. A necessity to measure the recoil spectra is stressed.
