DESCRIPTION:Speakers: Lakshya  Bhardwaj (Oxford U.)\, Ludovic Fraser-Talie
 nte (Oxford U.)\, Arthur Platschorre  (Oxford U.)\n\nThese 3 Zoom lectures
  aim to provide a comprehensive and in-depth introduction to Generalized s
 ymmetries for a broad audience of high-energy physicists interested in the
  theory and possible application of new symmetries. It includes three 90-m
 inute lectures scheduled for Januvery 2024 from 14:00 to 15:30 UK time\, J
 an 11th (Lakshya Bhardwaj on Higher-Form Symmetries and Confinement)\, Ja
 n 18th (Ludovic Fraser-Taliente on Higher-Form Symmetries and Anomalies)\,
  and Jan 25th (Arthur Platschorre on Non-invertible symmetries and Axions)
 . The lectures are based on Phys.Rept. 1051 (2024) 1-87.\n\nThird Lecture:
  25th Jan 2024\n14:00-15:30 UK time (15:00-16:30 CET)\n\nTitle: Non-invert
 ible symmetries and Axions\nSpeaker: Arthur Platschorre \n\nAbstract: T
 he aim of this final lecture is to explain the concept of non-invertible s
 ymmetries through an illustrative and phenomenologically relevant example\
 , the axion. In the presence of an axion-photon coupling\, the continuous 
 shift symmetry of the axion turns into a non-invertible symmetry. In gener
 al\, these non-invertible symmetries imply selection rules on correlation
  functions in the theory. In the case of the axion\, these symmetries cons
 train the general form of the axion-photon coupling. Furthermore\, in sing
 le axion models without domain wall problems\, the existence of such a sym
 metry constrains the allowed photon-coupling versus the mass parameter spa
 ce of the axion. Finally\, we note that the breaking of these non-invertib
 le symmetries by a suitable UV embedding of the standard model could allev
 iate the axion domain wall problem.\n\nFor the Zoom link and more informat
