We present a pedagogical review of particle physics models that are based on the noncommutativity of space–time, [Formula: see text], with specific attention to the phenomenology these models predict in particle experiments either in existence or under development. We summarize results obtained for high energy scattering such as would occur, for example, in a future e+e-linear collider with [Formula: see text], as well as low energy experiments such as those pertaining to elementary electric dipole moments and other CP violating observables, and finally comment on the status of phenomenological work in cosmology and extra dimensions.

In this paper we established model independent bounds on the anomalous magnetic and electric dipole moments of the tau-lepton using the process \mathbf{\gamma\gamma \to \tau^+\tau^-}𝛄𝛄→𝛕+𝛕−. We use data collected with the future \mathbf{e^+ e^-}𝐞+𝐞− linear collider such as the CLIC at \mathbf{\sqrt{s}}𝐬 = 380, 1500, 3000 GeV, and we consider systematic uncertainties of \mathbf{\delta_{sys}}𝛅𝐬𝐲𝐬 = 0\%%, 3\%%, 5\%%. The theory predictions are a very good prospect for probing the dipole moments of the tau-lepton at the future \mathbf{e^ + e^-}𝐞+𝐞− linear collider at the \mathbf{\gamma\gamma}𝛄𝛄 mode.

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 and tensor operators and apply our results for a phenomenological study of CP violation in the bottom and charm Yukawa couplings. We find large shifts of the induced Wilson coefficients at next-to-leading-logarithmic order. Using the experimental bound on the electric dipole moments of the neutron and mercury, we update the constraints on CP-violating phases in the bottom and charm quark Yukawas.
