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.

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.
