Abstract We present the contributions to electric dipole moments (EDMs) induced by the Yukawa couplings of an additional electroweak doublet of colour-octet scalars. The full set of one-loop diagrams and the enhanced higher-order effects from Barr-Zee diagrams are computed for the quark (chromo-)EDM, along with the two-loop contributions to the Weinberg operator. Using the stringent experimental upper limits on the neutron EDM, constraints on the parameter space of the Manohar-Wise model are… 

W-boson mass and electric dipole moments from colour-octet scalars

New coloured scalars in the Manohar-Wise model give sizeable contributions to the Electric Dipole Moment (EDM) of the neutron through one-loop and two-loop diagrams, computed in Reference [1].

Global fit on coloured scalars including the last W-boson mass measurement

We consider a simple extension of the electroweak theory, incorporating one SU (2) L doublet of colour-octet scalars with Yukawa couplings satisfying the principle of minimal flavour violation. Using



Electric dipole moment constraints on CP-violating heavy-quark Yukawas at next-to-leading order

Abstract Electric dipole moments are sensitive probes of new phases in the Higgs Yukawa couplings. We calculate the complete two-loop QCD anomalous dimension matrix for the mixing of CP-odd scalar

Reevaluation of Neutron Electric Dipole Moment with QCD Sum Rules

We study the neutron electric dipole moment in the presence of the CP-violating operators up to the dimension five in terms of the QCD sum rules. It is found that the OPE calculation is robust when

Unitarity and vacuum stability constraints on the couplings of color octet scalars

A bstractThe recent discovery of a 126 GeV boson at the LHC will be followed by a detailed examination of its couplings in order to determine whether this particle is the Higgs boson of the standard

Two Higgs doublet models augmented by a scalar colour octet

A bstractThe LHC is now studying in detail the couplings of the Higgs boson in order to determine if there is new physics. Many recent studies have examined the available fits to Higgs couplings from

Colored scalars and the neutron electric dipole moment

We investigate new contributions to the neutron electric dipole moment induced by colored scalars. As an example, we evaluate contributions coming from the color octet, weak doublet scalar,

Evolution of Weinberg's gluonic CP-violation operator.

The renormalization-group evolution of Weinberg's purely gluonic dimension-6 {ital CP}-violating operator is computed to first order in the QCD coupling constant, including its mixing with the quark
