SUMMARY:New Insights Into Lepton-Axion Interactions \, Network in Neut
 rinos\, Nuclear Astrophysics\, and Symmetries (N3AS) Seminar\, Jeff Dr
 or \, UCSC
DESCRIPTION:Axion-like particles (ALPs) below the electroweak scale ar
 e a simple\, natural extension to the Standard Model and\, as such\, a
 re one of the primary targets for the large-scale experimental effort 
 to search for hidden sectors. In this talk\, I revisit the theoretical
  framework of ALP interactions with leptons\, finding some unexpected 
 features in some amplitudes. Most importantly\, I will show that there
  exist strong bounds on "leptophilic" ALPs from a combination of charg
 ed meson decays\, W boson measurements\, and proton beam dump experime
 nts. These bounds dramatically shape allowed ALP parameter space and w
 ill be significantly improved with dedicated searches. <br>
