Abstract
Particle physics research informs us about the nature of matter on very small scales. As we step down the length scales below the length scale of the atom, 10^(-10) meters, and past the length scale of the atomic nucleus, 10^(-15) meters, we enter the realm of particle physics. In this realm there are three well identified interactions. First, the strong interactions, which are responsible for the binding of quarks and gluons to produce protons, neutrons and other particles collectively called hadrons. Second, the electroweak interactions, responsible both for the radiation of photons (light) from matter and the radiation of the carriers of the weak force, the W and Z bosons, discovered at CERN in the 1983. Third, the interactions of the Higgs bosons. The Higgs boson was discovered at CERN in 2012. The interactions of all of these ingredients are controlled by a mathematical structure, known as the Standard Model (SM) gauge theory of electromagnetic, weak and strong interactions. This theory has so far withstood all the challenges posed by various accelerators, of which the latest and most energetic is the LHC. The SM is confirmed - with the unification of electromagnetism and weak interactions proved and tested to one part per mille. Strong interaction effects have been tested to the percent level.
The quarks, the ingredients of the hadrons, come in six different types which are referred to as flavours. Flavour phenomena have contributed as much as the gauge principle in shaping the overall structure of the SM and it is the existence of flavours that gives the SM its family and generation structure. In the quark sector the SM description of flavour phenomena and the CKM picture of mixing and CP violation is now verified at the few per cent level. In the lepton sector, the flavours of leptons are the electron, the muon and the tau and their associated neutrinos. The observation of neutrino oscillations, and the consequence that neutrinos have mass, calls for an extension of the SM. Detailed examination of the charged and neutral leptons is of increasing importance.
Since 2015, the Large Hadron Collider (LHC) has been accelerating and colliding protons at much higher energies than ever before, close to the design energy of 14 TeV. This higher energy probes much shorter distance scales than ever before. The high energy reach of the LHC will also allow the detailed study of the Higgs boson and exploration of TeV scale physics. However, the LHC experiments are significantly more complex than any previous particle physics experiment. Identifying the nature of physics at the TeV scale will require intense collaborative efforts between experimentalists and theorists. On the theoretical side, high-precision calculations of SM processes are needed to distinguish possible signals of new physics from SM backgrounds. Possible hints of new physics need to be compared with different models of physics beyond the SM in order to disentangle the underlying structure of TeV-scale physics. The IPPP has already established close connections with the UK and international experimental groups and is perfectly placed to help maximise the UK contribution to understanding the LHC data.
There is also a strong effort in planning and designing the next generation of particle physics experiments. The IPPP will continue its role in assessing the physics potential and the design of future accelerators. The next decade promises to be pivotal in our understanding of the microscopic world. The IPPP will address fundamental questions about electroweak symmetry breaking, the structure of space-time, flavour physics and CP violation, neutrinos and lepton-flavour violation, and how particle physics connects with astrophysics and cosmology.

Planned Impact
The excitement of basic science can have impact beyond the limits of Academia. In order to fulfil that promise the IPPP attaches great importance to publicizing its activities to the wider public, and in particular to raising the awareness of particle physics in schools. IPPP is also committed to equipping our PhD graduates and RAs with the necessary skills and experience for a rewarding career in academic or industrial research.
Outreach
-IPPP benefits from a full-time outreach officer, funded by the University
-Our innovative outreach project Higgs to Hubble (https://www.dur.ac.uk/physics.outreach/) continues to have a positive impact by using our research to engage and enthuse school children, their teachers and the wider community and stimulate their interest.
-Since 2012 IPPP has acted as host for a bi-annual residential Ogden Trust A2 Physics Symposium.
-Our programme for the general public has provided a broad spectrum of talks through a variety of learned organisations, including the British Association, the Royal Institution and the Institute of Physics, and through the many regional and nationally coordinated science festivals.
-We also create original and relevant teaching resources based upon our research and use this material in workshops as part of Continuing Professional Development courses and training support sessions for teachers.
-We also host an annual one day event for local teachers. A Day for Everyone Teaching Physics is designed to extend both specialist and non specialist teachers knowledge and understanding of physics and provide ideas for practical activities for the classroom.
-Since Autumn 2015, we have run "Saturday Morning Physics", an annual series of 6 public lectures primarily aimed at high-school students, with an audience of up to 50.
Education & Training
-We train our PhD graduates and RAs with the necessary skills and experience to allow them how to think independently and critically, and use analytic and computational skills to solve complex problems.
-Together with our colleagues in the Department of Mathematical Sciences, we run a formal training programme in theoretical particle physics for PhD students (and also MSc students, via the MSc in Particle, Fields and Cosmology).
-The main areas IPPP can contribute to training are in the close supervision in research projects that aid the development of a wide range of skills including advanced software development, abstract thought, high performance computing, as well as the capability of collaborative research both locally and internationally.
