    "abstract": "The existence of a finite electric dipole moment (EDM) d_a of the\nclosed-shell atom Yb implies parity and time reversal violations involving the\nnuclear sector. An important effect which can contribute to the Yb EDM is the\ntensor-pseudotensor electron-nucleus interaction characterized by the coupling\nconstant C_T. Within the Standard Model (SM) of particle physics C_T=0, as this\nform of interaction is not allowed. If a finite d_a of Yb is observed in\nexperiments, then an estimate of C_T can be obtained by combining with the\ntheoretical calculations. A non-zero C_T implies physics beyond the standard\nmodel. In this paper we present the result of our ab initio calculation of the\nEDM Yb using different many-body methods.",
