Research Projects
Current research projects in Experimental Particle Physics include:
- The CMS (compact muon solenoid) experiment at the LHC, the world's highest energy collider, discovered the Higgs Boson in 2012. This discovery resulted in a Nobel Prize in 2013 and today, CMS is focused on precision measurements of the Higgs boson and searches for new physics. CMS has managed to place stringent limits on theories that go beyond the Standard Model. CMS is taking data at the highest energies and rates ever achieved and will continue its search for physics beyond the Standard Model. Once the high-luminosity LHC starts, CMS will be capable of taking data at a rate never before achievable. Breakthroughs in fast digital electronics and the use of machine learning will be vital for the CMS physics programme in the future.
- LHCb, an experiment at the LHC, which is searching for deviations from the Standard Model in the decays of B mesons. The experiment uses the LHC as a prolific source of B-hadrons, providing the potential for a discovery of physics not explained by the Standard Model in Rare Decays and in CP violation measurements. The existing measurements provide powerful probes of new physics models and have revealed intriguing deviations from the Standard Model expectations. Further measurements are now being started with the data collected after the LHC upgrade and these measurements will allow the deviations seen to be explored further.
- T2K/Super-K/Hyper-K, the experiment through which we made the seminal discovery of electron-neutrino appearance from a muon-neutrino beam, and which continues to be the neutrino beam experiment that is making the highest-precision measurements. We are working on the upgrade to the neutrino-beam line at J-PARC that is required to secure the best sensitivity for the T2K programme and on the Hyper-Kamiokande experiment, which is the next-generation experiment that will follow T2K.
- Ground-breaking research to transform the clinical practice of particle-beam therapy and to develop advanced concepts in particle acceleration are carried out within the the Centre for the Clinical Application of Particles (CCAP) the John Adams Institute for Accelerator Science. The CCAP is a multi-disciplinary collaboration with the mission to harness novel particle-acceleration, detection, imaging, and data-processing techniques for biomedical science and clinical application. At the heart of the Centre's programme is the development of the Laser-hybrid Accelerator for Radiobiological applications, LhARA. Accelerator R&D is centred on the development of novel techniques for high-power proton beams and the development of nuSTORM, a novel source of intense neutrino beams with precisely controlled flux and energy produced by the decay of muons confined within a storage ring. We are active in the development of a future muon collider and the study of ionization cooling, including the development of an experiment to demonstrate cooling in all 6 phase-space dimensions. We are also developing new concepts for Fixed Field Accelerators with application to ISIS (PDF) at RAL and future clinical application. We have a close collaboration with CNRS Institute Curie in Paris and the University of Santiago di Compostella, with several jointly supervised PhD students. PhD programmes are executed in collaboration with our partners at CERN, Daresbury and Rutherford Appleton Laboratories, and at other laboratories overseas.
- ASACUSA studies "half-matter"; half-antimatter atoms that contain antiprotons at CERN's Antiproton Decelerator and ELENA facilities. PiHe synthesises exotic atoms that contain pions. These atoms are irradiated by intense and highly monochromatic laser beams that excite transitions of the antiproton and pion orbitals. The latest quantum metrological techniques are used for this. By observing the associated quantum jumps, the antiproton and pion masses can be determined with unprecedented precision. This allows us to explore matter-antimatter symmetries and quantum electrodynamics which are the most precisely understood part of the Standard Model.
- SHiP is a proposal for a new facility at CERN that is led by Imperial group members. The experiment will search for the new particles predicted by so-called "Hidden Sector" models which are capable of accommodating dark matter, explaining the pattern of neutrino oscillations and masses, and the origin of the baryon asymmetry in the Universe.
- SBN, The Short Baseline Neutrino Program is a collection of three experiments located in the booster neutrino beam at Fermilab. The experiments are designed to study neutrino interactions with liquid-argon time projection chambers. The three experiments, SBND, MicroBooNE, and ICARUS, are located between 100 and 600 meters from the neutrino source of the booster.
- Preparations for the LISA experiment, a next generation gravitational wave experiment in space.
- LUX-ZEPLIN (LZ) is the leading dark matter search experiment, now starting operations at the Sanford Underground Research Facility. LZ is expected to produce world-leading results on various dark matter interactions and observe the scattering of astrophysical neutrinos - all during a PhD timescale. In parallel, R&D towards a future next-generation experiment is under way in our Liquid Xenon Laboratory. There are also opportunities to participate in the MIGDAL experiment which will soon start taking data at RAL; the Migdal effect enhances the search for light dark matter interactions in many detector technologies.
- COMET, an experiment to search for muon-to-electron conversion, a process that is yet to be seen, but which is extremely sensitive to deviations of the universe from the Standard Model. Phase-I of the experiment is under construction and is due to take data shortly, while a further phase is being designed, with construction scheduled in the next several years.
- DUNE is a next-generation long-baseline neutrino experiment in the USA. It will have the sensitivity to make a definitive discovery of leptonic CP violation and then precisely measure this phenomenon. DUNE also promises unprecedented sensitivity to neutrino-nucleus interaction physics and neutrinos from supernovae. We are working on physics sensitivity studies, and building parts of the near detector and the electronics and software that will acquire data from the experiment.
- AION The main objective of this project is to implement a fresh approach to atom interferometry (with single-photon transitions) that provides a novel method of detecting dark matter with a new instrument, as well as major advantages for the observation of gravity waves (GW) in the long term. This new quantum technology provides a major opportunity to push measurements beyond the current sensitivity limits in fundamental physics applications, e.g. for GWs in the mid-frequency band, around 1Hz. The AION collaboration is the culmination of extensive community building and will put the UK at the forefront of this globally important venture.
- Grid computing technologies required for carrying out the data processing in association with the LHC.
- Development of new classes of position detectors, based primarily on silicon, and designing the associated complex signal processing electronics
