Wboson mass and electric dipole moments from colouroctet scalars
Abstract
New coloured scalars in the ManoharWise model give sizeable contributions to the Electric Dipole Moment (EDM) of the neutron through oneloop and twoloop diagrams, computed in Reference [1]. Contributions from neutral scalars cancel out for degenerate values of the masses, whose difference is related to the oblique parameters $S$ and $T$. The ManoharWise model is able to explain the recent value of the $W$boson mass published by the CDF collaboration. We show, however, that the case of total degeneracy of masses is strongly disfavoured in this model, whose parameter space is substantially reduced when considering also unitarity bounds.
