On the Kinematic Reconstruction of $e^+e^\to W^+W^\to jj\tau\overline{\nu}_\tau$\ Events
Abstract
We show that the kinematic reconstruction of the $e^+e^\rightarrow W^+W^\rightarrow jj\tau^\overline{\nu}_\tau$\ events have a oneparameter ambiguity when reconstructed from the momentum of all measured $W^$\ decay products. We propose a {\em hybrid} method of reconstruction of the $e^+e^\rightarrow W^+W^\rightarrow jj\tau^\overline{\nu}_\tau$\ events. This is based on the observation that the difference between the $\tau^$\ production angles and the production angles of the sum of its visible decay products is small, whilst the $\tau^$\ energy is poorly reconstructed. This method consists of taking the $\tau^$\ production angles from those measured for the sum of the visible $\tau^$\ decay products and reconstructing the $\tau^$\ energy from energymomentum conservation constraints. A reconstruction using this method is found to be welldefined and possess a unique solution for the $\tau^$\ momentum range at LEP II and NLC.
