Invited talk

We present the status and plans of The Oscillating Resonant Group AxioN (ORGAN) Collaboration, which develops microwave cavity axion haloscopes to search for dark matter. ORGAN is a nation wide collaboration, with the main experiment hosted at The University of Western Australia.

Axions are a leading dark matter candidate. Axion haloscopes are a class of experiments which search for axion...

Coherent muon to electron conversion is a charged lepton flavour violating process that provides an exceptionally clear signature for new physics searches beyond the Standard Model. The COMET experiment at J-PARC in Tōkai, Japan, will search for this transition with a world leading single event sensitivity of $3×10^{−15}$ in Phase-I, scaling to $1×10^{−17}$ for Phase-II. The experiment...

The coherent muon to electron transition (COMET) experiment is searching for evidence of new physics via direct muon to electron decays in muonic aluminium, aiming to reach a sensitivity of $3\times10^{-15}$ in Phase-I and $1\times10^{-17}$ in Phase-II, a factor 10000 improvement. The detector system for Phase-I, currently under construction at the J-PARC facility in Japan, is comprised of a...
