A Possible Measurement of CP-Violation in B0-decays by ATLAS on LHC
  A possibility to measure CP-violation in B0-decays by ATLAS experiment was investigated. With one year of running at luminosity 10^33 cm-2s-1 with a muon pt-trigger threshold of 20GeV and rapidity coverage eta<2.5 of the tracking detector the rate of 1490 events B0->J/psi->mumupipi can be reached.
