| Abstract |
The production of tau-leptons in ep collisions is studied with the H1 detector at HERA by
using an identification algorithm based on the search for isolated charged tracks associated
to narrow hadronic jets detected in the calorimeters, a typical signature of the one-prong
hadronic tau decay. Using this identification procedure, a search for events with high-PT
isolated tau-leptons and missing transverse momentum is performed using a data sample
corresponding to an integrated luminosity of 108 pb^{-1} collected with the H1 detector
at HERA in the period 1996-2000 (HERA-I), and using the recent data collected in the
period 2003-2005 (HERA-II). This search complements the observation of isolated electrons
and muons in events with missing transverse momentum. In addition, a preliminary search for
events with tau-lepton pairs produced in elastic photon-photon collisions is performed. |
