Abstract
The B-physics potential of the ATLAS experiment at LHC is described. Simulation results are shown for the measurement of sin(2beta), with an emphasis on new tagging techniques. Other CP-violation measurements are described briefly. New limits are shown for the reach of the x_s-measurement, resulting from increased statistics and improved fitting methods. Some rare decay modes of B-mesons can be easily seen in ATLAS. Analyses of channels B-> mu+mu-(X) are presented here.
