Abstract
We briefly summarize some theoretical advances on perturbative QCD calculations relevant for the physics of the Large Hadron Collider (LHC). As an explicit example, we discuss the next-to-next-to-leading order (NNLO) QCD calculation for the production of a Higgs boson decaying to bottom quarks in association with a vector boson. We show illustrative numerical results for cross sections and associated distributions with typical kinematical cuts applied in the LHC experimental analysis.

Notes
- 1.
That is an observable independent of the number of soft and collinear final state particles.
- 2.
For a recent review about the state of the art on PDF determination see [4].
- 3.
Given the larger value of the QCD coupling compared to the electroweak one, at typical momentum scales of LHC processes, the impact of the electroweak corrections is in general less relevant.
- 4.
Jets are reconstructed with the flavour-\(k_T\) algorithm with \(R=0.5\) [35].
