      abstract     = {The 2012 discovery of the 12 GeV Higgs boson at the LHC,
                      and of no other particle since then, have brought a
                      consensus to the particle physics community that an e+e-
                      Higgs factory is the highest priority next collider.
                      However, Higgs measurements suffer from the loss of
                      undetected neutrino energy due to semi-leptonic decays
                      (SLDs) in the most common decay mode H to b anti-b. Previous
                      work has shown the possibility to reconstruct the missing
                      neutrino if the corresponding lepton and its production
                      vertex are found. Search algorithms for these leptons are
                      already in use to improve b-jet identification.In this work,
                      a novel BDT-based method to identify SLD electrons and muons
                      has been developed. Furthermore, a particle identification
                      (PID) method for electrons and muons from jets was also
                      built.The new PID can identify electrons with an efficiency
                      of $95\%$ and a purity of $98\%$ given that dE/dx
                      information is available. For muons, $74\%$ efficiency and
                      $89\%$ purity were reached. Combined with this new PID, the
                      developed SLD ID method can identify SLD electrons and muons
                      with an efficiency of $65\%$ and a purity of $77\%.$},
