Résumé |
The two parameters of the Standard Model that have the strongest impact on physics
at low energy are also the most sensitive to the details of the theory at high
energies. They are the cosmological constant and the Higgs boson mass.
Experimentally they are both associated to scales that we can measure.
Theoretically they force us to ask questions about physics at higher energies,
possibly all the way to the Planck scale. At the moment we do not understand their
measured values. The difficulty has the same origin for both parameters and can be
traced to the symmetries of fundamental interactions.
I will review how to state precisely the two problems and what are their possible
solutions, focussing mostly on the Higgs boson mass. The review will be concise
and aimed at highlighting the qualitative differences between distinct ideas, with
some attention devoted also to more recent and radical proposals. |
