Resumen

Permanent electric dipole moments (EDMs) in atoms or molecules are a signature of time-reversal and parity violation and represent an important window onto physics beyond the Standard Model. We are developing a next generation EDM search based on laser-cooled and trapped ²²⁵Ra atoms. Due to octupole deformation of the nucleus, ²²⁵Ra is predicted to be two to three orders of magnitude more sensitive to T-violating interactions than ¹⁹⁹Hg, which currently sets the most stringent limits in the nuclear sector. We will discuss progress toward realizing a first EDM measurement for ²²⁵Ra.
