      abstract     = {Supersymmetry (SUSY) with bilinearly broken R parity (bRPV)
                      offers an attractive possibility to explain the origin of
                      neutrino masses and mixings. In such scenarios, the study of
                      neutralino decays at colliders gives access to neutrino
                      sector parameters. The ILC offers a very clean environment
                      to study the neutralino properties as well as its subsequent
                      decays, which typically involve a $W$ or $Z$ boson and a
                      lepton. This study is based on ILC beam parameters according
                      to the Technical Design Report for a center of mass energy
                      of $500\,\mathrm{GeV}$. A full detector simulation of the
                      International Large Detector (ILD) was performed for all
                      Standard Model backgrounds and for
                      $\widetilde{\chi}_1^0$-pair production within a simplified
                      model. The bRPV parameters are fixed according to current
                      neutrino data. In this scenario, the $\widetilde{\chi}_1^0$
                      mass can be reconstructed with an uncertainty of $\delta m =
                      (40(\text{stat.}) + 50(\text{syst.}))\,\mathrm{MeV}$ for an
                      integrated luminosity of $500\,\mathrm{fb}^{-1}$ from direct
                      $\widetilde{\chi}_1^0$-pair production, thus, to a large
                      extent independently of the rest of the SUSY spectrum. The
                      achievable precision on the atmospheric neutrino mixing
                      angle $\sin^2 \theta_{23}$ from measuring the neutralino
                      branching fractions $\mathrm{BR}(\widetilde{\chi}_1^0
                      \rightarrow W \mu)$ and $\mathrm{BR}(\widetilde{\chi}_1^0
                      \rightarrow W \tau)$ at the ILC is better than current
                      uncertainties from neutrino experiments. Thus, the ILC could
                      have the opportunity to unveil the mechanism of neutrino
                      mass generation.},
