54. Dark Photon Limits: a Cookbook

Alexander Millar (Stockholm University)

6/16/21, 6:20 PM

The dark photon is a massive hypothetical particle that interacts with the Standard Model by kinetically mixing with the visible photon. Due to the similarity with the electromagnetic signals generated by axions, many putative bounds on dark photon signals are simply reinterpretations of historical bounds set by axion haloscopes. However, the dark photon has a property that the axion does not:...

104. HiRes Analysis of the ADMX Run 1c Data

The Axion Dark Matter Experiment (ADMX) aims to detect the decay of axions in the galactic halo into two microwave photons within a cavity. There are two main analysis channels for the experiment. One has a frequency resolution of 200 Hz and is called medium res. The second has a frequency resolution of 20 mHz and is called HiRes. The latest data taken was for run 1c., which uses a single...

114. Recent results from the Chandra analysis

Benjamin Safdi

6/16/21, 7:00 PM

Axions may be produced in abundance within compact stars such as white dwarfs and neutron stars. It has long been recognized that axion production in compact stars opens up a new pathway for them to cool. I will point out, however, that axions may also lead to novel X-ray signatures around these stars, whereby the axions are produced within the stellar cores and then convert to photons in...
