Xianguo Lu

Ernest Rutherford Fellow

My name is Xianguo Lu, or 卢显国 (Mandarin Chinese pronunciation). I am an experimental physicist studying elementary particles like ​neutrinos.

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). I was a postdoc in heavy ion physics at the University of Heidelberg, and then in neutrino physics at the University of Oxford before moving on to become an STFC Ernest Rutherford Fellow. I am also a Senior Research Fellow in Pembroke College.

I am an unambitious but regular runner, having run a little more than 300 kilometres in 2020. I particularly enjoy running during my travel. The following are some of my memorable moments:

  • 5 km Île de la Cité-Île Saint-Louis, Paris, France, July 2019,
  • 5 km in Venice, Italy, June 2019,
  • 12 km in Central Park, New York, US, July 2018, and
  • 10 km around Lake Senba, Mito, Japan, February 2018.

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 topics:

  • 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 work with 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.

For potential DPhil thesis topics, please feel free to contact me via E-Mail or visit Thesis Topics.

In 2015, I developed the idea of using transverse kinematic imbalance [Phys. Rev. D 92, 051302 (2015), Phys. Rev. C 94, 015503 (2016)], or TKI, to precisely identify intranuclear dynamics, or the absence thereof, in neutrino-nucleus interactions—an analogue of the missing energy technique used in collider experiments. Since then, I have been introducing this new technique to neutrino experiments including T2K, MINERvA, DUNE, and MicroBooNE to pursue in-depth understanding of the nature of neutrinos.

Recent activities

As Analysis Co-Coordinator of the MINERvA Experiment, I contribute to defining the analysis plan of the collaboration.

In the DUNE Experiment, we are analysing the data from ProtoDUNE at CERN, the prototype detector of the DUNE liquid argon Far Detector. 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)].

A list of selected publications can be found here.

Past activities

  • Development of the TKI technique and pioneering measurements in the T2K Experiment in Japan and the MINERvA Experiment in the US. A list of idea papers and measurements that I was directly involved in can be found here.
  • Measurements of identified-hadron yields in jets at the ALICE experiment at CERN [Quark Matter 2014 proceedings].
  • ALICE time projection chamber (TPC) and transition radiation detector (TRD) performance studies—awarded ALICE Best Technical Thesis for 2013 [thesis].
  • Combined-asymmetry measurements of deeply virtual Compton scattering, or DVCS, at the HERMES Experiment at DESY in Germany. I was responsible for developing the signal extraction method. The published measurements can be found here.
