Measurement of physical parameters with a weight function method and its
application to the Higgs boson mass reconstruction    [PDF]

We propose a new method to measure various physical parameters, using characteristic weight functions. This method needs only lepton energy distribution and ideally does not depend on the velocity of the parent particle. We demonstrate an application of this method by simulating a reconstruction of the Higgs boson mass in the H-> WW -> lnu lnu decay mode at the LHC. We show that systematic errors are suppressed compared to statistical errors. In the vector boson fusion channel, the statistical accuracy of the mass determination is estimated to be +12% and -14% at an integrated luminosity of 100fb^{-1}, assuming the Higgs mass to be 125GeV and root{s}=14TeV.
