講演題目: The ACME experiment: An improved limit on the electron's electric dipole moment
講演要旨
Searches for violations of discrete symmetries can be sensitive probes of
physics beyond the Standard Model. Many models introduce new particles at
higher masses that generally include new CP-violating phases which are
thought to be of order unity. Such phases could generate measurable
electric dipole moments (EDMs) of fundamental particles. The ACME
collaboration(*) has measured the electron's EDM to be consistent with zero
with an order of magnitude improvement in precision compared to the
previous best precision. This limit constrains time-reversal violating
physics for particles with masses well into the TeV scale. This talk will
describe the ACME experiment, its systematic errors, and upgrades that are
in progress.
(*)The ACME Collaboration: ACME(=Advanced Cold Molecule Electron EDM) is
a collaboration between Harvard University and Yale University, led by
Professors Doyle, Gabrielse and DeMille. The experiment itself is
located in the Physics Department at Harvard.
