The ATLAS Detector Physics Potential

The high energy and high luminosity of the LHC pp collider should offer a 
very rich physics programme. The Standard Model Higgs boson should be 
discovered over the full range of allowed masses, and its mass and 
coupling parameters should be measured with a sufficient accuracy. 
Theories beyond the CM, such as Supersymmetry, Technicolour, new gauge 
bosons, compositness and Extra dimensions will also be probed. Several 
precision measurements will be made in the B-physics sector, in the top 
sector and in the electroweak sector (W mass, Triple Gauge Couplings, 
etc.) leading to significant improvements on the precision achieved by  
previous experiments. This talk will highlight some of the recent studies 
performed by ATLAS in the context of new theoritical development and 
detector performance studies.
