Higgs-boson mass and the strength ofCPviolation

Abstract

We examine the possibility that $\mathrm{CP}$ violation is of the microweak type and is generated via exchanges of Higgs bosons with masses as high as ∼ ${10}^3$ GeV. Working in the context of the Weinberg-Salam theory we build a model in agreement with the experimental data. The neutron's dipole moment is estimated to be of the order of $\sim {10}^{-26\mathrm{}} e$ cm, a result which can be tested by the next round of measurements of $D_E^{\left(\mathrm{neutron}\right)}$ Under the assumption that the heavy-Higgs-boson exchanges are the only sources of $\mathrm{CP}$ violations, estimates for the impurity parameters ${\epsilon }_D$, ${\epsilon }_B$, ${\epsilon }_T$ of the $D^0-{\overline{D}}^0$, $B^0-{\overline{B}}^0$, and $T^0-{\overline{T}}_0$ systems are given.
