Exploring the Higgs Sector at Particle Colliders

by Dr Stephen Jones (Durham University)


After the discovery of the Higgs boson at the Large Hadron Collider (LHC) in 2012, we have now entered a new era of precision high-energy physics. This precision is the key to making new discoveries, as even slight deviations from the Standard Model will provide important hints towards as yet unknown particles and interactions. However, with experimental precision at the high luminosity upgrade to the LHC (HL-LHC) expected to outstrip theoretical uncertainties, the success of this program will rely on our ability to overcome the immense challenges involved in improving the accuracy of our theoretical predictions. In particular, we will need to calculate higher-order quantum corrections which are beyond the scope of current methods.

In this talk we will take a look at some of the modern developments in computing perturbative QCD and EW corrections and discuss a variety of methods that have allowed this theoretical progress to be made.
