Abstract. QCD is an extensively developed and tested gauge theory, which models

the strong interactions in the high-energy regime. In this talk, I shall

review the considerable progress which has been achieved in the last

few years in the most actively studied QCD topics: Monte Carlo models,

higher-order corrections, and parton distribution functions.

Thanks to that, QCD in the high-energy regime

is becoming more and more an essential precision tool kit to analyse

Higgs and new physics scenarios at the LHC.

Keywords. Hadron-induced high-energy interactions;

jets in large-Q2 scattering; perturbative calculations; factorization.
