Comment on the preprint: First Limits on Axion Dark Matter from a DALI Prototype arXiv:2603.21951

Abstract

We report on an independent assessment of the sensitivity of the DALI setup to axion-like particle (ALP) dark matter, as described in [1]. Our analysys is based on the information provided in the preprint and using the formalism developed within the MADMAX collaboration. We do not identify any mode below 12 GHz with significant coupling to the axion field to account for the reported sensitivity. We provide recommendations for assessing the axion coupling of electromagnetic modes in dielectric haloscope experiments.
