Theoretical study of ${}^{173}$YbOH to search for the nuclear magnetic quadrupole moment

Abstract

CP-violating interaction of the nuclear magnetic quadrupole moment (MQM) with electrons in the ytterbium mono-hydroxide molecule, ${}^{173}$YbOH, is considered. Both the magnetic quadrupole moment (MQM) of the ${}^{173}$Yb nucleus and the molecular interaction constant WM 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 EDM, QCD vacuum angle $\theta$, quark EDM and chromo-EDM.
