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 Mode — such as models that incorporate supersymmetry — 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 electron’s spin.  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. Here, I share with you the exciting journey of the ACME electron EDM search that has set the current best limit on the value of electron EDM, measured by spin precession in a superposition of quantum states in cold molecules.  This result severely constrains T-violating new physics in 3~30 TeV energy range, exceeding what can be reached at the Large Hadron Collider.  New upgrades are now underway, projecting over an order-of-magnitude sensitivity enhancement for the next EDM search.
