Data intense large order Feynman graph evaluation

The PhD Studentship lies in the area of Theoretical Particle Physics, now entering an exciting new era of high precision physics. A wealth of novel and interesting results are anticipated at currently running experiments (CERN, Fermilab, J-PARC, KEK, PSI), with the main goal to observe evidence for new particles and new physics. This will provide

the much needed information and direction to construct theories that extend the Standard Model of particle physics. Disentangling such "Beyond the Standard Model" events, expected to be rare, requires theoretical input and in particular very precise calculations. The core formalism for this is the evaluation of Feynman graphs in a

perturbative expansion in the coupling strength of the particle interactions. High order results are now absolutely necessary to meet the precision demanded by experiments. To achieve this involves evaluating Feynman integrals whose number increases exponentially with coupling constant order. The underlying techniques and algorithms to achieve this

are data intensive and require significant computer management. The studentship sits within this framework and it is envisaged that the specific topic for the project will lie in the strong and electroweak sector of the Standard Model including the Standard Model Effective Theory. Throughout the project the student will have access to our comprehensive postgraduate

training in Theoretical Particle Physics as well as targeted training in data science provided by LIV.INNO. The student will also have the opportunity to carry out a six month work placement in order to broaden their wider research and career skills. This will be within one of the software engineering teams at STFC's DiRAC High Performance

Computing facility with centres.
