Professor Michael Seymour
University of Manchester
My research is at the frontier between theory and experiment in particle physics. I make advances in theoretical understanding and calculations, use them to develop more accurate simulations of particle physics events, and more powerful ways to use the data to measure the underlying physics and discover new physics. Much of this involves working closely with experimenters to raise their awareness of theoretical issues that affect their analyses, and understanding small details of the analyses that can have a significant impact on the accuracy of their conclusions.
In more detail, my expertise is in the theory of the strong nuclear force, which describes the behaviour of quarks and gluons, and how they are confined together into particles like the proton. Since the LHC collides together protons, but we are mainly interested in the production of much more massive particles, a detailed understanding of these interactions is needed to predict and analyse events.
My work has directly impacted on many LHC analyses, most notably the discovery of the Higgs boson and measurements of its properties, using my Monte Carlo simulation tools, analysis tools that I developed and theoretical calculations made by others using a technique I developed.
In the last year the largest areas of my activity have continued to be in improving the Monte Carlo simulations that all the LHC experiments use to model their events and extract fundamental physics parameters from those events, working closely with the experimenters using them to analyse the data from the LHC, and developing a deeper understanding of the theory behind LHC event simulation.
My work has a significant impact on the exploitation of the LHC and so, more widely, on the general understanding of our physical world.
