Description

We propose a new method to measure the top quark mass at the LHC. This method requires only lepton energy distribution and is basically independent of the production process of the top quarks. With this method, the MSbar mass of the top quark can be determined. We perform a simulation analysis of the top quark mass reconstruction with ttbar pair production and lepton+jets decay channel at the leading order. Estimated uncertainties in the top mass reconstruction are about 1.5GeV with an integrated luminosity of 100fb^{-1} at root{s}=14TeV. The uncertainties are expected to be improved by including higher-order corrections.
