Many of our PhD studentships include the opportunity to work in one of the major particle physic labs for a period of up to 18 months.
Possible PhD topics in the Liverpool Particle Physics group include:
Physics at the energy frontier with the ATLAS experiment.Supervisors: Jan Kretzschmar, Sergey Burdin, Andy Mehta, Max Klein, Uta Klein, Monica D’Onofrio, Yangan Gao and Nikolaos Rompotis
The first run of the ATLAS experiment at only half its ultimate centre-of-mass energy led to the discovery of the Higgs boson in 2012 as well as a lot of other exciting physics results.
The LHC has since been upgraded and restarted in 2015 at the full 13 TeV centre-of-mass energy. This has opened a window for the ATLAS experiment to search for new physics which may exist given our current understanding of the Universe. New physics ought to be discovered, either in searches for new particles and phenomena or in precise measurements of processes involving already discovered particles, including the Higgs, W and Z bosons and the top quark. Our ATLAS group offers PhD projects in all areas of this broad physics programme. The ATLAS group also has a strong involvement in the R&D for the ATLAS Silicon tracking detectors.The Liverpool group is designing and will build upgraded trackers with state-of-the art technology for the upgrade of the LHC to allow much higher luminosities to be collected. PhD project are also available within the hardware development activity.
Many of our PhD positions offer the possibility of spending an extended period at CERN. We also have offer joint positions with the DESY research centre in Hamburg Germany, where your time would be spent between Liverpool and Hamburg with the possibility of extended visits to CERN.
Neutrino PhysicsSupervisors: Neil McCauley, Costas Andreopoulos, Kostas Mavrokoridis, Christos Touramanis and Joachim Rose
The neutrino group at Liverpool has a wide experimental programme examine the key questions in neutrino physics. We study neutrino oscillations and search for CP violation utilising long baselines at the T2K experiment in Japan and are preparing the next generation of these experiments at DUNE in the US and at Hyper-Kamiokande in Japan. We search for neutrinoless double beta decay to measure neutrino mass and the character of neutrinos at the SNO+ experiment in Canada.
Locally in Liverpool we carry out research and development for the next generation of neutrino detectors using liquid Argon. We have recently secured ERC funding for the development of a two phase liquid argon detector utilizing a novel camera readout approach (ARIADNE). Opportunities are available across our programme, for example at T2K you will get the opportunity to spend some time in Japan supporting the ECAL operation of the near detector. You will also perform neutrino oscillation studies.
Physics at the energy frontier with the LHCb experimentSupervisors: Themis Bowcock, David Hutchcroft, Tara Shears
The LHCb experiment, at the LHC, is designed to investigate CP-violation, search for New Physics, and perform precise studies of W and Z bosons in a region unexplored by other experiments. Our group has a strong involvement in the LHCb electroweak and B physics programmes, and we offer PhD places in both areas. We also have responsibility for running the main silicon detector, and will construct its replacement for the upgrade to LHCb; giving opportunities for involvement in hardware construction and testing to interested students.
Charged lepton flavour violation in the mu2e (Fermilab) and mu3e (PSI) experiments.
Supervisors: Joost Vossebeld, Themis Bowcock and Laura Harkness-Brennan
The Liverpool group will start a participation in the mu2e and mu3e experiments at Fermilab and PSI. Two experiments that wlook for evidence of charged lepton flavour violation (cLFV) in extremely rare (less than 1 in 1016) muon decay processes. Critical detector components are foreseen to be built in Liverpool. In particular, Liverpool expects to host a major part of the construction of the mu3e MuPix HV-CMOS tracker and of the mu2e Stopping Target Monitor Germanium detectors. Assembly work for these activities will start in April 2017.
PhD students on these experiments would join the research teams working on the development and construction of these detectors and on quality assurance measurements for the HV-CMOS and germanium detectors. For mu3e first data will arrive in 2018 and we expect students to also work on the preparation for the analysis of these first data and ultimately to contribute to the first publications of the experiment on cLFV muon decays. By early 2019, mu3e results are expected to outperform the current world-best limits from the previous SINDRUM experiment.
The proposed programme will offer you an excellent training by having the opportunity within the PhD to contribute to the construction, commissioning, simulation and physics phase of a single experiment. There will be periods during which you will travel regularly to PSI or Fermilab.
The Search for Dark Energy with Atom Interferometry
Supervisor: Jon Coleman
An experiment is under development for to investigate “dark energy” in the Universe by means of laboratory experiments which push at the “precision frontier” to find deviations from expectation given present understanding of the laws of physics. The consequences of dark energy have the potential to show up terrestrially. An atom interferometer is being developed with the aim of probing anomalous gravitational effects which could be due to the dark contents of the vacuum and can be interpreted as dark energy.
Reactor Monitoring with Antineutrinos
Supervisor: Jon Coleman
The Particle Physics group at the University of Liverpool is carrying out tests of prototype anti-neutrino detector for Reactor Monitoring. After successful tests at the Wylfa nuclear reactor, the detector has been returned to Liverpool to undergo a series of upgrades. There is the opportunity for interested students to be involved in all parts of the experiment from the development of detection technology to the modelling and analysis of ant-neutrino data from the reactor.
Development of High Voltage CMOS pixel detectors for future physics experiments
Supervisors: Joost Vossebeld, Gianluigi Casse
The industry standard HV-CMOS technology is a novel attractive solution for tracking charged particles in high energy physics experiments. The Liverpool PP group works on the development sensors using this technology to meet the challenging requirements on tracking detectors of future experiments in particle physics. Examples are the Future Circular Collider proton proton (FCC-pp) facility, the Compact Linear Collider at CERN (CLIC), The LHCb phase 3 VeLo detector upgrade, a polarimeter for a future proton EDM experiment or the high beam rate 2nd phase of the mu3e experiment at PSI.
Working with the team in Liverpool and our partners at FBK CMM (Trento), students will be closely involved with the active international R&D programme on HV-CMOS technology. They will work on the design and layout of the circuitry for these "smart sensors" using advanced design software packages. The student will also actively participate in the evaluation of prototype devices in laboratory and in test-beam measurements. The student would share his or her time between Liverpool and FBK-CMM. The research work has a high content of applied physics and detector science and will provide advanced skills in these areas.
Supervisor: Sergey Burdin
Existence of Dark Matter which has mass 5 times higher than the mass of ordinary matter in the Universe is supported by many astronomical measurements. There are strong indications that some unknown Weakly Interacting Massive Particles (WIMPs) make the largest contribution to the Dark Matter. Therefore a lot of searches for New Physics are motivated by the Dark Matter. These searches could be divided into 3 subgroups: indirect, collider and direct. The direct searches look for interactions of Dark Matter particles with ordinary matter and a positive result in these searches would provide the most compelling explanation for the Dark Matter.
LZ is a large scale 2nd generation experiment being built for the direct Dark Matter searches. It has been approved by both DOE (USA) and STFC (UK). The LZ experiment will have the best sensitivity among all the experiments with similar timescale for particles with masses from 10GeV to 10TeV. The LZ detector will consists of 7 tonnes of liquefied xenon as the target material which will be surrounded by outer detector made of gadolinium loaded liquid scintillator (20 tonnes) and water (230 tonnes). The detector will be based in the former Homestake gold mine (South Dakota, USA) at the depth of about 1 mile. Though the rocks will protect the detector from cosmic radiation, the water and liquid scintillator will form an additional active veto system protecting from very rare remaining cosmic muons as well as from external and internal radiation.
The Liverpool group joined the LZ project in 2014. The technical contribution to the project is the optical calibration system for the outer detector. The Liverpool group will be actively involved into the data analysis.
The detector installation will start in 2019 with data taking in 2020. The PhD project will be devoted to the tests, construction and validation of the optical calibration system; simulation of the signal and background events in the LZ detector and in particular in the outer part; analysis of the first data from the LZ experiment. Being an Outer Detector expert the student will be leading neutron background studies which are essential for the DM results. The timing of the PhD starting in October 2017 is perfect for the LZ project as the student will participate in all the crucial stages of the experiment.
