Model-independent sensibility studies for the anomalous dipole moments of the ${\nu }_{\tau }$ at the CLIC based $\gamma e^{-}$ colliders

Abstract

To improve the theoretical prediction of the anomalous dipole moments of the $\tau$-neutrino, we have carried out a study through the process $\gamma e^{-}\to \tau {\bar{\nu }}_{\tau }{\nu }_e$, which represents an excellent and useful option in determination of these anomalous parameters. To study the potential of the process $\gamma e^{-}\to \tau {\bar{\nu }}_{\tau }{\nu }_e$, we apply a future high-energy and high-luminosity linear electron-positron collider, such as the CLIC, with $\sqrt{s}=380,1500,3000GeV$ and $\mathcal{L}=10,50,100,200,500,1000,1500,2000,3000f{b}^{-1}$, and we consider systematic uncertainties of ${\delta }_{sys}=0,5,10\%$. With these elements, we present a comprehensive and detailed sensitivity study on the total cross-section of the process $\gamma e^{-}\to \tau {\bar{\nu }}_{\tau }{\nu }_e$, as well as on the dipole moments ${\mu }_{{\nu }_{\tau }}$ and $d_{{\nu }_{\tau }}$ at the $95\%$ C.L., showing the feasibility of such process at the CLIC at the $\gamma e^{-}$ mode with unpolarized and polarized electron beams.
