Heavy flavor physics with CMS

Different recent results from CMS Collaboration on Quarkonia Physics and Heavy Quarks production are presented. All these results have been obtained analyizing the data of $pp$ collisions at sqrt{s}=7 TeV provided by the LHC and collected by the CMS detector in the year 2010. The measurements of B-mesons, charmed mesons and open beauty production cross--sections are illustrated, together with the analysis techniques and the estimation of the systematics uncertainties, and compared with the predictions of the available theoretical models. A recent result from CDF on the Upsilon polarization is also reported.

Measurements of Inclusive b-quark Production at 7 TeV with the CMS Experiment

Measurements performed by the CMS experiment of the cross section for inclusive b-quark production in proton-proton collisions at sqrt(s) = 7 TeV are presented. The measurements are based on different methods, such as inclusive jet measurements with secondary vertex tagging or selecting a sample of events containing jets and at least one muon, where the transverse momentum of the muon with respect to the closest jet axis discriminates b events from the background. The results are compared with predictions based on perturbative QCD calculations at leading and next-to-leading order.
