Measurement of the b-hadron production cross section using decays to D *+ μ - X final states in pp collisions at √s = 7 TeV with the ATLAS detector

The b-hadron production cross section is measured with the ATLAS detector in pp collisions at s=7TeV, using 3.3pb -1 of integrated luminosity, collected during the 2010 LHC run. The b-hadrons are selected by partially reconstructing D z.ast;+ μ - X final states. Differential cross sections are measu...
