| The reconstruction of tau pairs coming from very energetic objects (Z,H) can be affected from the fact that if the boost is high enough the two taus can be very collimated and the final decay products of one can enter the reconstruction (and/or isolation) con of the other. Then the standard identification techniques for hadronic taus, electrons and muon will fail. | The reconstruction of tau pairs coming from very energetic objects (Z,H) can be affected from the fact that if the boost is high enough the two taus can be very collimated and the final decay products of one can enter the reconstruction (and/or isolation) con of the other.
