Tau lepton reconstruction at collider experiments using impact parameters

Abstract

We present a novel method for the reconstruction of events containing pairs of hadronically decaying tau leptons at collider experiments. This method relies on accurate knowledge of the tau production vertex and precise measurement of its charged decay products. The method makes no assumptions about the centre-of-mass or invariant mass of the tau pair, and is insensitive to momentum loss along the beam direction. We demonstrate the method using e+e- -> mu+ mu- tau+ tau- events fully simulated in the ILD detector.
