Motiv<strong>at</strong>ion for <strong>NLO</strong><br />
Stabilizing the scale in the QCD input parameters:<br />
Strong coupling constant and PDFs<br />
More reliable theoretical error rel<strong>at</strong>ed to the scale dependence<br />
Normaliz<strong>at</strong>ion and shape <strong>of</strong> distributions first known <strong>at</strong> <strong>NLO</strong><br />
Many scale processes: V+ jets, ttH, tt + jets, bb + jets, njets ...<br />
How do we know which scale to choose ?<br />
Improved description <strong>of</strong> jets<br />
Jets: LO <strong>NLO</strong> Parton Hadron<br />
