For those behind a pay wall, here's the arxiv version, https://arxiv.org/abs/2212.11841
As someone who knows nothing about high energy physics, my naive questions are: 1) why is it such a big deal that electrons don't have electric dipole moment, but it's OK to have no magnetic monopole, and start right at the order of dipole? 2) wouldn't alternating domains of matter / antimatter resolve the apparent asymmetry? Has this scenario been ruled out experimentally?
