Abstract:The Standard Model of particle physics accurately describes all fundamental particles discovered so far. However, it is unable to address two great mysteries in physics, the nature of dark matter and why matter dominates over antimatter throughout the Universe. Novel theories beyond the Standard Model may explain these phenomena. These models predict very massive particles whose interactions violate time-reversal (T) symmetry and would give rise to an electric dipole moment (EDM) along the spin of electron and nucleon. Thus, searching for EDM provides a powerful probe to these new physics and sheds light on the mystery of the matter-antimatter asymmetry of the Universe.
This talk outlines the roadmap to establish a new generation EDM measurement at Michigan State that can outperform the current generation of precision measurements testing hadronic T-violations. We report our ongoing effort at FRIB to perform quantum control and sensing of 227ThO molecules and other radioactive molecules. These pave the way for quantum-enhanced test of fundamental symmetry, projecting to constrain T-violating new physics in 10~100 TeV energy range, exceeding what the Large Hadron Collider and its future upgrade could probe.
