DPhil in Particle Physics
About the course
The work of this world-class sub-department is in experimental particle physics, particle astrophysics and accelerator physics. Particle physics is the study of basic constituents of matter and their interactions. This is accomplished either directly with accelerators that create the particles under study or by observing high-energy particles from outer space.
The sub-department is one of the largest in the UK and is well equipped to carry out research in a wide range of topics, from the study of new particles produced at high energy accelerators to neutrinos, dark matter and dark energy in the Universe. The sub-department’s experiments are carried out at facilities around the world, in Switzerland, Japan, the USA and Canada.
You will spend half the first year on a lecture course in addition to starting your research and, if appropriate, spend your second year on-site at your experiment. Laboratories here in Oxford and experiments at overseas facilities provide access to a high-tech environment and excellent research training, directly applicable to a broad range of fields.
The world's biggest accelerator, the Large Hadron Collider (LHC) at CERN, is running and in 2012 the Higgs boson, a particle thought to give mass to all elementary particles, was discovered. The understanding of its properties is one of the main aims of the ATLAS experiment. The Oxford group is also focused on the search of new particles predicted in Supersymmetry and others beyond the Standard Model theories. Elucidation of CP violation, one of the mysteries of particle physics, is the aim of the sub-department’s other LHC experiment, LHCb. Both experiments will require you to obtain and analyse data from the highest-energy machine in the world.
The sub-department is also involved in the study of neutrino oscillations and neutrino properties at the T2K experiment in Japan, MicroBooNe & DUNE in the USA, and at the Sudbury Neutrino Observatory (SNO+) in Canada.
The sub-department has participated in direct searches for dark matter for many years and studentships are now available associated to the LZ project. Recently it has begun a programme in collaboration with the sub-department of astrophysics to elucidate the nature of dark energy with the Large Synoptic Survey Telescope (LSST).
The future of particle physics relies on the development of new instruments for detecting particles and novel ideas in accelerator physics. The sub-department is heavily involved in the development of these areas. It has outstanding facilities to build the new silicon detectors needed for the luminosity upgrade of the LHC and other applications.
The sub-department is playing a major role in the ProtoDune experimental program at CERN, which is designed to test and validate the Liquid Argon Time Projection Chamber technologies for the construction of the DUNE Far Detector at the Sanford Underground Research Facility (SURF).
Furthermore, through the John Adams Institute, students can engage in a range of projects on accelerators which would be used in high energy physics, nuclear physics, as X-ray sources, and in medical applications.
The allocation of graduate supervision for this course is the responsibility of the Department of Physics and it is not always possible to accommodate the preferences of incoming graduate students to work with a particular member of staff. Under exceptional circumstances a supervisor may be found outside the Department of Physics.
You will be allocated at least one supervisor who should be your primary contact for guidance throughout your research degree. Research students join an existing research group which typically consists of academics, postdocs, fellows and current students. Students will meet with supervisors regularly. This could be in person, via email, or video conferencing.
All students will be initially admitted to the status of Probationer Research Student (PRS). Within a maximum of six terms as a PRS student and normally by the fourth term you will be expected to apply for transfer of status from Probationer Research Student to DPhil status.
A successful transfer of status from PRS to DPhil status will require satisfactory attendance and completion of problem sets during your first two terms, and submission of a report and thesis outline. Submission on a report and thesis outline. Students who are successful at transfer will also be expected to apply for and gain confirmation of DPhil status within nine terms of admission, to show that your work continues to be on track.
Both milestones normally involve an interview with two or more assessors other than your supervisor and therefore provide important experience for the final oral examination (ie the viva).
The actual DPhil viva requires you to submit a [substantial and original] thesis not exceeding 250 pages after three or at most four years from the date of admission. To be successfully awarded a DPhil in particle physics you will need to defend your thesis orally (viva voce) in front of two appointed examiners.
The particle physics doctoral programme at Oxford is ideally suited to students who would like to pursue a career in research, either in academia or industry all over the world.
Students have taken on a wide variety of jobs in other fields, including investment banking, business analysis, and consulting. Physics as a discipline is always in high demand.
Changes to this course and your supervision
The University will seek to deliver this course in accordance with the description set out in this course page. However, there may be situations in which it is desirable or necessary for the University to make changes in course provision, either before or after registration. The safety of students, staff and visitors is paramount and major changes to delivery or services may have to be made in circumstances of a pandemic (including Covid-19), epidemic or local health emergency. In addition, in certain circumstances, for example due to visa difficulties or because the health needs of students cannot be met, it may be necessary to make adjustments to course requirements for international study.
Where possible your academic supervisor will not change for the duration of your course. However, it may be necessary to assign a new academic supervisor during the course of study or before registration for reasons which might include illness, sabbatical leave, parental leave or change in employment.
