Job description

# Research Assistant/Associate in HEP TheoryA position exists for a Research Assistant/Research Associate in High Energy Particle Physics Theory and Phenomenology. The aim of the role is to work in theoretical particle physics, developing cutting-edge, high-precision calculations in the Standard Model relevant for LHC phenomenology and future colliders. The role holder is expected to have excellent knowledge of theoretical particle physics with particular emphasis on developing and/or using high-precision calculations for LHC processes.The successful candidate will hold (or be close to obtaining) a PhD in Theoretical Physics with a proven track record in precision calculations for hadron colliders. Preference will be given to candidates with experience in NLO, NNLO or N3LO calculations, calculations of multiloop/multileg amplitudes and matching parton showers with higher order calculations, heavy flavour physics, as demonstrated by publications in major journals. Solid computational skills are essential, and the successful candidate will also have proven organisational, communication and team working skills.Please ensure you upload your Curriculum Vitae (CV) together with a list of publications and a covering letter including a 2-4 page summary of your research interests and future plans.
