In this paper, we present a method to reconstruct the $t \\bar{t}$ decay in the dilepton channel at future $e^+e^-$ colliders. We derive a simple, closed analytical expression for the neutrino four-momenta as a function of the $W$ boson mass and develop a maximization procedure to find the optimal solution for the reconstruction of the full $t \\bar{t}$ event. We show that our method is able to reconstruct neutrino four-momenta with an error of less than $2 \\, \\%$ i","authors_text":"J. M. Moreno, P.
