An improved analysis framework for axion dark matter searches

Publikováno v: Phys. Rev. D 101, 123011 (2020)

In experiments searching for axionic dark matter, the use of the standard threshold-based data analysis discards valuable information. We present a Bayesian analysis framework that builds on an existing processing protocol to extract more information

Results from phase 1 of the HAYSTAC microwave cavity axion experiment

Publikováno v: Phys. Rev. D 97, 092001 (2018)

We report on the results from a search for dark matter axions with the HAYSTAC experiment using a microwave cavity detector at frequencies between 5.6-5.8$\, \rm Ghz$. We exclude axion models with two photon coupling $g_{a\gamma\gamma}\,\gtrsim\,2\ti

Design and Operational Experience of a Microwave Cavity Axion Detector for the 20-100 micro-eV Range

We describe a dark matter axion detector designed, constructed, and operated both as an innovation platform for new cavity and amplifier technologies and as a data pathfinder in the $5 - 25$ GHz range ($\sim20-100\: \mu$eV). The platform is small but

First results from a microwave cavity axion search at 24 micro-eV

Publikováno v: Phys. Rev. Lett. 118, 061302 (2017)

We report on the first results from a new microwave cavity search for dark matter axions with masses above $20~\mu\text{eV}$. We exclude axion models with two-photon coupling $g_{a\gamma\gamma} \gtrsim 2\times10^{-14}~\text{GeV}^{-1}$ over the range

Publikováno v: Phys. Rev. Lett. 112, 241302 (2014)

We report a first search for weakly interacting massive particles (WIMPs) using the background rejection capabilities of SuperCDMS. An exposure of 577 kg-days was analyzed for WIMPs with mass < 30 GeV/c2, with the signal region blinded. Eleven events

The SuperCDMS experiment in the Soudan Underground Laboratory searches for dark matter with a 9-kg array of cryogenic germanium detectors. Symmetric sensors on opposite sides measure both charge and phonons from each particle interaction, providing e
