In this paper the production cross-section pp → (γ, Z) → ν τντ γ+X in pp collisions at √ s = 13, 14, 33 T eV is presented. Furthermore, we estimate bounds at the 95% C.L. on the dipole moments of the τ-neutrino using integrated luminosity of L = 100, 500, 1000, 3000 f b −1 collected with the ATLAS detector at the LHC and we consider systematic uncertainties of δ sys = 0%, 5%, 10%. We found that the current and future LHC bounds are weaker than other experiments reported in the literature. However, it is shown that the process under consideration is a good prospect for probing the dipole moments of the τ-neutrino at the LHC.

It is known that the dipole moments of the neutrino lead to important astrophysical and cosmological effects. In this regard, within the context of a U (1) B−L model, we develop and present novel analytical formulas to assess the effects of the anomalous magnetic moment and electric dipole moment of the neutrino on the stellar energy loss rates through some common physical process of pair-annihilation e + e − → (γ, Z, Z ′ ) → ν ν. Our results show that the stellar energy loss rates strongly depends on the effective magnetic moment of the neutrino, but also on the parameters which characterize the adopted U (1) B−L model.

Probing the electromagnetic dipole moments of the tau-neutrino in theU(1)B−Lmodel at the ILC and CLIC energies

Abstract: In this work we study the sensitivity on the anomalous magnetic and electric dipole moments of the tau-neutrino in the framework of theat future e + e − linear colliders as the ILC and CLIC. For our study we consider the process
