Résumé |
The questions surrounding the microscopic nature of dark matter and the origin of
the scale of weak interactions are among the deepest open problems in particle
physics. After a decades-long experimental program we have found no sign that
their traditional solutions are realized in Nature, leaving us to wonder how to
move forward. In this talk I will discuss a new connection between these two
questions that involves another long-standing problem in particle physics (the
minuscule size of the neutron electric dipole moment) and the particle postulated
to solve it, the axion. This change of theoretical perspective has important
consequences for experiment that I will explore in the second part of the talk,
where I outline a new experimental program for the next decade. |
