Theoretical study of 173YbOH to search for the nuclear magnetic quadrupole moment

A CP-violating interaction of the nuclear magnetic quadrupole moment (MQM) with electrons in the ytterbium monohydroxide molecule (YbOH)-Yb-173 is considered. Both the MQM of the Yb-173 nucleus and the molecular interaction constant W-M are estimated. Electron correlation effects are taken into account within the relativistic Fock-space coupled-cluster method. Results are interpreted in terms of the strength constants of CP-violating nuclear forces, neutron dipole moment (EDM), QCD vacuum angle theta, quark EDMs, and chromo-EDMs.
