Job description

Applications are invited for up to 2 Postdoctoral Research Associate 2+1 year positions at the Higgs Centre for Theoretical Physics

One position will work on higher order QCD corrections to LHC observables: infrared subtraction and asymptotic expansions. One position will work on the mathematical structure of multi-loop scattering amplitudes and the development of bootstrap methods for computing them.

QCD corrections to LHC observables

The successful candidates will contribute to the European Research Council Consolidator Grant project “Feynman Graph Expansions for high Precision”. Research activities include computing Feynman amplitudes for cross section calculations relevant for the LHC. We are seeking applications from candidates with expertise in higher-order QCD corrections: both real and virtual corrections, soft-collinear effective theory and resummation, and scattering amplitudes.

Mathematical Structure

The successful candidates will contribute to the European Research Council Starting Grant project “The Perturbative Scattering Amplitude Bootstrap”. Research activities include developing a better understanding of the mathematical structure of scattering amplitudes, and leveraging this understanding to develop efficient bootstrap methods for computing amplitudes in supersymmetric theories and in the Standard Model.

Appointments can be made at Grade 7: £41,064 to £48,822 per annum.

The closing date for applications is the 5th of January 2026. Please send your references to [e-mail] quoting job numbers 13231 and 13229 by the closing date.
