Resumen:
To improve the theoretical prediction of the anomalous dipole moments of the τ -neutrino, we have
carried out a study through the process γe− → τν¯τ νe, which represents an excellent and useful option
in determination of these anomalous parameters. To study the potential of the process γe− →
τν¯τ νe, we apply a future high-energy and high-luminosity linear electron-positron collider, such as
the CLIC, with √
s = 380, 1500, 3000 GeV and L = 10, 50, 100, 200, 500, 1000, 1500, 2000, 3000 f b−1
,
and we consider systematic uncertainties of δsys = 0, 5, 10%. With these elements, we present a
comprehensive and detailed sensitivity study on the total cross-section of the process γe− → τν¯τ νe,
as well as on the dipole moments µντ and dντ at the 95% C.L., showing the feasibility of such process
at the CLIC at the γe− mode with unpolarized and polarized electron beams.
