Query: Lepton identification performance in Jets at a future electron positron
  Higgs Z factory   Identifying the leptons inside jets is critical for the measurements of Higgs
boson and the flavor physics program at the CEPC, a proposed Higgs/Z factory
with the main ring circumference of 100 km. Using the CEPC baseline software,
we analyze the identification performance of leptons generated inside a jet.
The jet leptons are identified with typical efficiency and mis-identification
rate of 98% and 1% for energy higher than 2 GeV, with the $Z\to bb$ process at
91.2 GeV center-of mass energy. At the benchmark channel of the CEPC flavor
program of $B_{c}\to \tau\nu$ with $\tau \to e\nu\nu$, the electrons are
identified with inclusive efficiency times purity of 97%, providing sufficient
signal selection for the physics potential study. Compared to the single
leptons, we found that these jet leptons identification efficiency degrades
about 1-3%, and the mis-identification rate increases by less than 1% at the
same working point. We analyze this effect and found that it is mainly caused
by defects in the particle flow reconstruction code in the calorimeters. The
dependence between the performance of the shower reconstruction and the lepton
identification is quantified.
