PhD project

Probing the Higgs boson is a critical priority in the search for new physics at the Large Hadron Collider (LHC). To this end, collisions containing a Higgs and a top-quark pair (ttH) are especially well motivated. The candidate will play a leading role in new differential measurements of ttH. This will provide fresh sensitivity to the strength of the top-Higgs interaction and the Higgs self-interaction which are directly related to the stability of the Universe at a quantum level. Furthermore, the exact nature of the top-Higgs interaction could hold the answer to why we exist at all - why the Universe is matter-dominated.

Top quarks produced with lepton pairs (ttll) are a key background to ttH, but are also vital to probe one of the strongest hints of new physics to from the LHC – the flavour anomalies. The candidate will also measure ttll (where l=e,mu,tau) to test the universality of lepton couplings in the top sector. This will add vital additional information to understand the flavour anomalies seen in the B-sector.

The ATLAS-Sussex group has made significant contributions measurements of ttH, ttW and ttZ so far in ATLAS: profiting from this experience in the group, the candidate will be ideally positioned to make large impact in this area, supported by contact with CERN-based experts. 

Funding is available for a September 2023 start which includes a tax-free bursary (£17,668 per annum in 2022/23) and fully paid (at the Home student level) tuition fees for 3.5 years. Additional financial support is provided to cover short-term and long-term travel. Interviews of shortlisted candidates will be held in February and March initially and will continue until positions are filled. Applications from self-funded students interested in available projects are also welcome at any time of the year.


Applicants must hold, or expect to hold, at least a UK upper second class degree (or non-UK equivalent qualification) in Physics, or a closely-related area, or else a lower second class degree followed by a relevant Master's degree.

This award is open to UK and International students.
