High p$_T$ EWK and QCD results from CMS

The LHC has been delivering data to CMS at a centre-of-mass energy of 7 TeV since April 2010, with an instantaneous luminosity that has been constantly increasing from $10^{27}$ to $10^{31}$ cm$^{-2}$s$^{-1}$. Both the machine and the detector have given outstanding performance. The detector communi...

Sumario:The LHC has been delivering data to CMS at a centre-of-mass energy of 7 TeV since April 2010, with an instantaneous luminosity that has been constantly increasing from $10^{27}$ to $10^{31}$ cm$^{-2}$s$^{-1}$. Both the machine and the detector have given outstanding performance. The detector community has been very fast to deliver physics results, which have already extended the transverse momentum reach of the Tevatron. This review will concentrate on preliminary results obtained with between 60 nb$^{-1}$ and 1.7 pb$^{-1}$ of data: inclusive jet and dijet production, 3-jet to 2-jet ratio, W/Z boson decays into leptons including W+jets and first observation of taus, and top quark studies in the dilepton and lepton+jet channels.
