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.

The Standard Model of particle physics\, while providing an excellent description of experime ntal data\, leaves key observations unexplained\, most notably the existen ce of dark matter. It also raises deep theoretical puzzles\, such as the i nstability of the Higgs mass in the presence of heavy physics. As conventi onal solutions to these problems have not emerged at the expected energy s cales\, it is now crucial to rethink our approach towards physics beyond t he Standard Model (BSM). This talk gathers my latest efforts to explore BS M 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 trad itional models can point to novel and unexplored regions of parameter spac e\, while maintaining their original purpose. I will also discuss novel st rategies based on effective field theory to probe more exotic origins of t he Higgs boson. In the second part\, I will turn to BSM scenarios characte rized by more feeble interactions. I will discuss novel aspects of QCD axi on phenomenology arising from its interplay with additional scalar fields\ , which reshape the landscape of axion dark matter searches.


Throughout the talk\, I will emphasize the i mportance of refining the map between data and a given particle physics mo del\, to fully explore the unprecedent data which will be gathered by futu re collider and astrophysical experiments.
