In this paper the production cross-section pp\rightarrow (\gamma, Z) \to \nu_\tau \bar \nu_\tau \gamma+Xpp→(γ,Z)→ντν‾τγ+X in pppp collisions at \sqrt{s}=13, 14, 33\hspace{0.8mm}TeV is presented. Furthermore, we estimate bounds at the 95\%95% C.L. on the dipole moments of the \tauτ-neutrino using integrated luminosity of {\cal L}= 100, 500, 1000, 3000 \hspace{0.8mm}fb^{-1} collected with the ATLAS detector at the LHC and we consider systematic uncertainties of \delta_{sys} = 0\%, \, 5\%, \,10\%δsys=0%,5%,10%. We found that the current and future LHC bounds are weaker than other experiments reported in previous investigations. However, it is shown that the estimated process is a good prospect for probing the dipole moments of the \tauτ-neutrino at the LHC.

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.
