Radiative in Left-Right Universal Seesaw
Tatsuya Banno, Junji Hisano, Teppei Kitahara +1
We investigate radiative corrections to the QCD parameter in the minimal left-right symmetric model with a universal seesaw mechanism, where parity symmetry ensures $\barθ=…
Full Three-Loop Electroweak Multiplet Contributions to the Electron Electric Dipole Moment
Tatsuya Banno, Junji Hisano, Teppei Kitahara +2
Experimental sensitivity to the electric dipole moment (EDM) of the electron has improved remarkably in recent years. Consequently, future prospects could probe new physics whose c…
Two-loop corrections to QCD angle from evanescent operator in the BMHV scheme
Tatsuya Banno, Junji Hisano, Teppei Kitahara +2
We study the renormalization of the QCD angle at the two-loop level focusing on divergent and finite -violating contributions from evanescent operators, using dimensional r…
Impact of the Electroweak Weinberg Operator on the Electric Dipole Moment of Electron
Tatsuya Banno, Junji Hisano, Teppei Kitahara +2
Recent progresses in the measurements of the electric dipole moment (EDM) of the electron using the paramagnetic atom or molecule are remarkable. In this paper, we calculate a cont…
Closer look at the matching condition for radiative QCD parameter
Tatsuya Banno, Junji Hisano, Teppei Kitahara +1
In this paper, we scrutinize a radiatively generated QCD parameter at the two-loop level based on both full analytical loop functions with the Fock-Schwinger gauge method and t…
Novel loop-diagrammatic approach to QCD parameter and application to the left-right model
Junji Hisano, Teppei Kitahara, Naohiro Osamura +1
When the QCD axion is absent in full theory, the strong problem has to be explained by an additional mechanism, e.g., the left-right symmetry. Even though tree-level QCD $\bar…
Contribution of the Weinberg-type operator to atomic electric dipole moments
Naohiro Osamura
We report the calculation of the isovector CP-odd interaction generated by the Weinberg operator, the CP violating three-gluon operator. This enables to restrict models which…
Contribution of the Weinberg-type Operator to atomic and nuclear electric dipole moments
Naohiro Osamura, Philipp Gubler, Nodoka Yamanaka
The contribution of the CP violating three-gluon Weinberg operator, , to the atomic and nuclear EDMs is estimated using…
