We present a feasibility study of top-quark mass measurement using the lepton energy distribution in the top-quark decay $$t \rightarrow bW \rightarrow b\ell \nu $$t→bW→bℓν at the LHC. The method used in this study requires only the lepton energy distribution at parton level. The analysis is performed in the lepton + jets final state by using fast simulation data corresponding to an integrated luminosity of approximately 20 fb$$^{-1}$$-1 at $$\sqrt{s}$$s = 14 TeV. Events with exactly one lepton…
