Theoretical study of HfF$^+$ cation to search for the T,P-odd interactions
Abstract
The combined all-electron and two-step approach is applied to calculate the molecular parameters which are required to interpret the ongoing experiment to search for the effects of manifestation of the T,P-odd fundamental interactions in the HfF cation by Cornell/Ye group [Science 342, 1220 (2013); J. Mol. Spectrosc. 300, 12 (2014)]. The effective electric field that is required to interpret the experiment in terms of the electron electric dipole moment is found to be 22.5 GV/cm. In Ref. [Phys. Rev. D 89, 056006 (2014)] it was shown that another source of T,P-odd interaction, the scalar-pseudoscalar nucleus-electron interaction with the dimensionless strength constant can dominate over the direct contribution from the electron EDM within the standard model and some of its extensions. Therefore, for the comprehensive and correct interpretation of the HfF experiment one should also know the molecular parameter the value of which is reported here to be 20.1 kHz.
