Title:   "Recent Results from the ATLAS Experiment in Searches 
           with Tau Lepton Final States".

Abstract:

A number of Beyond the Standard Model scenarios can lead to 
physics processes with $\tau$ leptons in the final state. The 
experimental detection of an excess of such events could 
indicate the existence of neutral Higgs bosons 
$h/A/H\rightarrow\tau^+\tau^-$) from the Minimal Supersymmetric 
extension to the Standard Model (MSSM), charged Higgs bosons 
$H^{\pm}\rightarrow\tau^{\pm}\nu$,third-generation leptoquarks, 
or even extra gauge bosons decaying into two $\tau$ leptons such 
as a $Z^{\prime}$ as predicted by Grand Unified Theories or theories 
of extra dimensions.  The most recent search results from the ATLAS 
experiment at the Large Hadron Collider (LHC) will be presented.
