First Search for Dark Photon Dark Matter with a madmax Prototype

J. Egge, D. Leppla-Weber, S. Knirck, B. Ary dos Santos Garcia et autres

We report the first result from a dark photon dark matter search in the mass range from 78.62 to 83.95 μeV/c^{2} with a dielectric haloscope prototype for madmax (Magnetized Disc and Mirror Axion eXperiment). Putative dark photons would convert to detectable photons …

First mechanical realization of a tunable dielectric haloscope for the MADMAX axion search experiment

B. Ary dos Santos Garcia, D. Bergermann, A. Caldwell, Vipul Dabhi et autres

Abstract MADMAX, a future experiment to search for axion dark matter, is based on a novel detection concept called the dielectric haloscope. It consists of a booster composed of several dielectric disks positioned with μm precision. A prototype composed of one movable …

First Search for Axion Dark Matter with a MADMAX Prototype

Berenice García, D. Bergermann, A. Caldwell, Vipul Dabhi et autres

This Letter presents the first search for dark matter axions with mass in the ranges 76.56 to 76.82 μeV and 79.31 to 79.53 μeV using a prototype setup for the MAgnetized Disk and Mirror Axion eXperiment (MADMAX). The experimental setup employs a …

Results on neutrinoless double beta decay of 76Ge from GERDA Phase I

M. Agostini, M. Allardt, E. Andreotti, M. Balata et autres

Neutrinoless double beta decay is a process that violates lepton number conservation. It is predicted to occur in extensions of the Standard Model of particle physics. This Letter reports the results from Phase I of the GERmanium Detector Array (GERDA) experiment at …
