Description
Why the Higgs boson mass is at the electroweak scale and not at the GUT or Planck scale constitutes what is called the `hierarchy problem'. I will discuss how attempts to cure this problem have fueled various speculations of physics `Beyond the standard model (BSM)'. I will briefly touch upon the electroweak precision measurements to highlight how we got clues about the Higgs mass from there. Then in specific BSM contexts, I will discuss how fine-tuned supersymmetry is (specifically after the Higgs discovery), and comment on the status of the `alternative' avenues leading to electroweak symmetry breaking (like `little Higgs' or `composite Higgs').
