Journal Publications

Here's my listing from Spires, the particle physics database of publications, and here's the same from google scholar.

Book

Together with John Campbell and Joey Huston I authored The Black Book of Quantum Chromodynamics, a primer on QCD in the LHC era.

Research Areas

My research area is the phenomenology of particle physics - this is the branch of theoretical physics that bridges the gap between theorists who construct more abstract models for the fundamental interaction of the constituents of the matter in the Universe at the smallest distances, and the experimenters that search for and measure phenomena, for example at the LHC at CERN. Phenomenologists use these models, new and old, to make predictions for observables in experiments or to calculate quantities that allow the experimenters to interpret their data as measurements of fundamental quantities.

My role in this is the construction of a simulation tool that tries to describe the experimental reality in great detail. Tools such as the ones I work on are also called event generators, since they generate "events", the plethora of particles that are produced when particles smash into each other at large energies. In these relatively violent collision the large energies of the incident beam particles are translated into showers of elementary particles which hit the detector at velocities very close to the speed of light. Event generators are the workhorses of particle physics, and are deployed for a wide range of purposes: Their output -- the simulated events -- is utilised to better understand detector responses to the interaction with incident particles, to help in the planning of analyses by providing an understanding of interesting signals and their backgrounds, to subtract backgrounds from signals, and to compare the most precise calculations directly with data. To fulfil these functions, they must contain all relevant physics, from the highest energies of the order of a few TeV down to the relatively low scales of MeV that characterise hadron physics. Traditional methods of evaluating quantum field theories, based upon the perturbative expansion in coupling constants, cannot fulfil this, due to two limitations: The sheer number of outgoing particles leads to a computational complexity we cannot conquer yet, and many of the produced particles are hadrons, bound states of the fundamental quarks and gluons, which form the hadrons in a phase transition that we cannot yet describe in a quantitative way. These two problems are addressed in event generators by decomposing the simulation into different phases, characterised by vastly different energy scales.

The event generator project I work on - now for more than 15 years - is called SHERPA.

We are a team of about 10 people or so from 5 countries on two continents, who work on the development, maintenance, deployment and validation of our tool.

To be more specific (and more for the specialists), here are my current research topics:

  • better description of perturbative QCD radiation through parton showers
  • the connection of the parton showers to the hard sub-process - by now this can be done at next-to leading order accuracy in Sherpa for practically arbitrary processes and at next-to-next-to leading order for two relatively simple ones
  • automatic calculation for multi-leg processes in - nearly arbitrary - models (matrix element generation and phase spacing)
  • the interface to non-perturbative QCD (fragmentation of the partons into colourless hadrons)
  • multiple interactions and the structure of hadrons
  • (new) physics at collider experiments

In addition, I collaborate with experimenters from the ATLAS collaboration on measurements of Double Parton Scattering - events where more than one pair of energetic quarks or gluons collides inside a single proton-proton scattering and gives rise to highly energetic particles.

Currently, I am one of two co-directors of the Durham Centre for Doctoral Training in Data-Intensive Science, held between our colleagues from Astronomy and the IPPP. We have a cohort of 15 students funded between STFC and Durham University who started in 2017 and another 7 students who started in October 2018.

Saturday Morning Science

In 2015 I introduced "Saturday Morning Physics", a series of 6-8 lectures for the general public. In 2018, we promoted this to Saturday Morning Science, a series of 22 lectures that cover research interests from all departments in the faculty of Sciences.
