The measurement of the muon inclusive differential cross section dsigma/dpT
in pp collisions at sqrt(s)=7 TeV with the ATLAS detector is presented. The
analysis is performed in the pseudorapidity interval |eta|< 2.5 for muon of
transverse momentum 4 < pT < 100 GeV and with an integrated luminosity of 1.4
pb-1. The result is compared with the next-to-leading order with
next-to-leading log high pT resummation prediction for the heavy avour
production and with MC@NLO prediction for W-Z bosons production. The
measurement is sensitive for the first time to the next-to-leading log
contribution to the heavy flavour production in hadronic interactions.Comment: 3 pag, 2 figures, proceedings for the conference PIC2011, Vancouver,
