Xianguo Lu

Ernest Rutherford Fellow

My name is Xianguo Lu, or 卢显国 (Mandarin Chinese pronunciation). I am a nuclear and particle physicist studying elementary particles, including

  • electrons and positrons whose interactions with nuclei could explain what gives rise to the building blocks of the visible Universe,
  • laboratory-made quark-gluon plasma that resembles the early Universe right after the Big Bang, and
  • neutrinos and antineutrinos that might provide the answer to why the Universe is dominated by matter over antimatter and therefore our world exists.

I got my BSc. from Peking University (2007), Diplom-Physiker from the University of Hamburg (2009), and Dr. rer. nat. from the University of Heidelberg (2013).

For potential DPhil thesis topics in

  • DUNE (Near Detector R&D and protoDUNE data analysis) and
  • JUNO (physics sensitivity study)

please feel free to contact me via E-Mail or visit Thesis Topics.

I started tutoring physics at Pembroke College in 2015. From 2016 (2017) to 2019, I was (Career Development) Stipendiary Lecturer in Physics. I covered the following courses:

  • 1st Year Physics,
  • Optics,
  • Statistical and Thermal Physics,
  • Quantum Mechanics,
  • Quantum Atomic and Molecular Physics,
  • Subatomic Physics, and
  • Symmetry and Relativity.

In the Particle Physics Subdepartment, I supervise research students at different stages. I also enjoy working with Summer Interns from across the world. I created the VISOS project for undergraduate research on neutrino oscillation phenomena.

Past activities

  • Combined-asymmetry measurements for generalised parton distributions, or GPDs, at the HERMES Experiment at DESY in Germany.
  • Measurements of identified-hadron yields in jets at the ALICE experiment at CERN.
  • ALICE time projection chamber (TPC) and transition radiation detector (TRD) performance studies—awarded ALICE Best Technical Thesis for 2013.
  • Development of the analysis method of transverse kinematic imbalance (TKI) to precisely identify intranuclear dynamics, or the absence thereof, in neutrino-nucleus interactions, and
  • follow-up measurements in the T2K Experiment in Japan and the MINERvA Experiment in the US.

Recent activities

As Analysis Coordinator in MINERvA, I support analysers to navigate the MINERvA physics landscape, that is expanded by

  • electron-and muon-flavoured neutrinos and antineutrinos of energy 1-10 GeV
  • interacting on hydrogen, carbon, iron, and lead targets,
  • with well reconstructed final-state electrons, muons, pions, protons, and neutrons.

In the DUNE Experiment, we are analysing the data from ProtoDUNE at CERN, the prototype detector of the DUNE liquid argon Far Detector, with the following objectives:

  • to study the detector performance in measuring hadrons, and
  • to extract intranuclear dynamics of the argon nucleus using TKI,

both of which are crucial to DUNE's neutrino oscillation measurements via GeV-neutrino interactions on argon. We are also working on the development of a high-pressure TPC for the DUNE Near Detector, in particular on a new design that can allow optimal neutrino-hydrogen measurements [Phys. Rev. D 102, 033005 (2020)].

In addition, I am a member of the T2K Experiment, and an invited collaborator of the MicroBooNE Experiment.
