Abstract.

Using the effective Lagrangians formalism, we study the radiative process \( pp\rightarrow (\gamma, Z) \rightarrow \nu_{\tau} \bar{\nu}_{\tau} \gamma +X\) in pp collisions at \( \sqrt{s}=\)8, 13, 14, 33 TeV. Furthermore, we estimate limits at the 95% C.L. on the dipole moments of the tau-neutrino using integrated luminosities \( \mathcal{L}=\)20, 50, 100, 200, 500, 1000, 3000 fb-1 collected with the ATLAS detector at the LHC and we consider systematic uncertainties \( \delta_{sys}=\)0, 5, 10%. We found that the LHC at high energy and high luminosity should provide the following limits on the anomalous magnetic and electric dipole moments of the tau-neutrino: \( \tilde{\kappa}_{\nu_\tau} = 1.251\times 10^{-6}\) and \( \tilde{d}_{\nu_\tau} = 2.424\times 10^{-17}\) ecm at 95% C.L. for \( \sqrt{s} =33\) TeV and \(\mathcal{L}=3000\) fb-1. We conclude that the process under consideration is a good prospect for probing the dipole moments of the tau-neutrino at the LHC. Our study complements other studies on the dipole moments of the tau-neutrino at pp, \( e^{+}e^{-}\), \( \gamma e^{-}\) and \( \gamma\gamma\) colliders.
