Description
The Haloscope At Yale Sensitive To Axion CDM (HAYSTAC) experiment is a microwave cavity search which is actively probing QCD axions with masses ≳$10\mu$eV. In this talk, I will present recent results from HAYSTAC's Phase II search for QCD axions between $16.96-19.46\mu$eV. These results are the widest search to date to achieve a quantum enhanced scan rate from a squeezed state reciever and include new data covering $1.71\mu$eV of previously unexplored parameter space with sensitivity to QCD axions with axion-photon coupling of $\sim3\times$$|g^{KSVZ}_{\gamma}|$. I will also discuss upgrades in development to facilitate further searches for axions beyond $20\mu$eV.
