DESCRIPTION:Speakers: Pierre Brun\n\nThe axion is a compelling extension o
 f the Standard Model\, introduced to address a longstanding puzzle in QCD.
  I will briefly review the theoretical motivation for introducing a new gl
 obal U(1) symmetry and its associated pseudo-Nambu–Goldstone boson\, the
  axion. Remarkably\, the resulting particle is also a natural dark matter 
 candidate. I will illustrate this connection by calculating the axion reli
 c density and discussing the conditions under which axions can account for
  the observed dark matter abundance. Requiring the axion to constitute the
  dark matter places significant constraints on its mass and interaction sc
 ale\, providing a well-defined target for experimental searches. I will us
 e this as a starting point to review the main experimental strategies for 
 axion dark matter detection\, from traditional narrow-band resonant search
 es to broadband approaches designed to explore a wider mass range. I will 
 conclude with DAWA\, an experiment being developed at Saclay to pursue bro
 adband searches for axion dark matter.\n \nzoom connection : https://cern
