Dr Alexander Mitov is a Lecturer, Cavendish Laboratory, University of Cambridge, UK. Dr Mitov is deeply involved in the phenomenology of the Large Hadron Collider, and is one of the leading theorists working in high energy applications of the strong interactions. His most recent major accomplishment, namely the calculation of the NNLO heavy quark pair hadroproduction cross section, has been on the list of “most wanted” results for almost a couple of decades. It is nowadays an essential ingredient to match the excellent precision of the measurements at the LHC, and its achievement represents a milestone result that will become textbook material. 

With the discovery of the “Higgs” particle, the main challenge for the particle physics community is to demonstrate the (possible) existence of beyond the Standard Model Physics. Furthermore, we would like to discriminate between the many proposed models of new physics. It is commonly accepted that the LHC will be able to provide us with the experimental input we need in order to answer these questions.

The experience from extensive searches for new physics at past and current particle colliders clearly demonstrates that in order to detect possible new physics effects, high- accuracy theoretical predictions for key observables in the Standard Model are needed. 

High-precision calculations for the LHC are still rare. But thanks to new advances in calculational techniques, important classes of LHC processes like top pair production, dijets, Higgs+jet and b-quark production can now be computed with high precision.

The timing for this breakthrough in precision calculations is remarkable because it coincides with another milestone: the expected (early 2015) start of the LHC at maximum energy. Having such high-precision results in time for the analyses of LHC data will represent a rare scientific opportunity. Exploring it is the subject of the present research proposal.

“It was a great opportunity and experience.”
