Results from phase 1 of the HAYSTAC microwave cavity axion experiment

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 \(g_{a\gamma\gamma}\,\gtrsim\,2\times10^{-14}\,\rm GeV^{-1}\), a factor of 2.7 ab...

Description
Summary: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 \(g_{a\gamma\gamma}\,\gtrsim\,2\times10^{-14}\,\rm GeV^{-1}\), a factor of 2.7 above the benchmark KSVZ model over the mass range 23.15$\,
