research program overview

Since we have no information on their particle nature or mass of dark matter, the Centre’s program covers a wide mass range. CDM research is organised in four integrated Research Program areas:

Program 1: Direct Detection

(6 nodes, 35 researchers, 28 RHD students)

The Centre’s program covers a wide range of putative dark matter particle masses with Australian based experiments using above-ground precision quantum techniques at UWA and deep underground experiments in SUPL. The ORGAN experiment (UWA) is producing data and the SABRE South experiment (SUPL) is in the construction phase. The Centre is producing new direct detection technologies to extend our dark matter searches via our robust R&D program.

Program 2: Precision Metrology

(2 nodes, 8 researchers, 9 RHD students)

Selecting ultra-pure materials for the underground experiments requires the development of excellent ultra-low background radioactivity measurements. The Centre is exploiting ANU and ANSTO Accelerator Mass Spectrometry (AMS) to develop ultrasensitive radioactivity measurement techniques for lead 210. UWA will develop ultra-precise measurements frequencies needed for sub eV dark matter searches.

Program 3: Large Hadron Collider Searches

(2 nodes, 8 researchers, 14 RHD students)

Dark matter searches with Run3 data at the ATLAS experiment at the Large Hadron Collider at CERN (Switzerland) are expanding our experimental reach to dark matter masses and interactions in regions where the direct detection experiments have less sensitivity.

Program 4: Dark Matter Theory

(5 nodes, 18 researchers, 37 RHD students)

The Centre’s theoretical program unites and underpins the experimental programs. If dark matter is discovered, this program will develop the theoretical framework to describe dark matter particles and their interactions, incorporating dark matter into a new fundamental theory of nature. It informs and helps interpret the Centre’s experimental results, drives future searches and fosters strong particle-astrophysics links.
