DESCRIPTION:The Standard Model of particle physics\, while providing an ex
 cellent description of experimental data\, leaves key observations unexpla
 ined\, most notably the existence of dark matter. It also raises deep theo
 retical puzzles\, such as the instability of the Higgs mass in the presenc
 e of heavy physics. As conventional solutions to these problems have not e
 merged at the expected energy scales\, it is now crucial to rethink our ap
 proach towards physics beyond the Standard Model (BSM). This talk gathers 
 my latest efforts to explore BSM beyond the standard paradigm.In the first
  part\, I will revisit long-standing expectations for new physics near the
  electroweak scale. I will show that non-minimal versions of traditional m
 odels can point to novel and unexplored regions of parameter space\, while
  maintaining their original purpose. I will also discuss novel strategies 
 based on effective field theory to probe more exotic origins of the Higgs 
 boson. In the second part\, I will turn to BSM scenarios characterized by 
 more feeble interactions. I will discuss novel aspects of QCD axion phenom
 enology arising from its interplay with additional scalar fields\, which r
 eshape the landscape of axion dark matter searches.Throughout the talk\, I
  will emphasize the importance of refining the map between data and a give
 n particle physics model\, to fully explore the unprecedent data which wil
 l be gathered by future collider and astrophysical experiments.
