Early b physics at ATLAS

We present measurements of J/psi, Upsilon and D mesons. We find that the ATLAS detector performance is well described by MC and invariant mass peaks are clearly seen. The shape of differential cross section of J/psi in data agrees well with MC. However the normalization of MC is found to be almost a...

description We present measurements of J/psi, Upsilon and D mesons. We find that the ATLAS detector performance is well described by MC and invariant mass peaks are clearly seen. The shape of differential cross section of J/psi in data agrees well with MC. However the normalization of MC is found to be almost an order of magnitude higher than one of data. The ratio of non-prompt J/psi to prompt J/psi agrees well with MC.
