Five leading scientists share their excitement about neutrino physics and discuss the challenges they are faced with.

Neutrinos may be key to tackling deep questions about the Universe, such as the existence of new physics beyond the predictions of the accepted model of particle physics. There are many things we don't yet fully understand about these elusive particles, and to search for answers physicists rely on large high-precision instruments built in unusual places, such as the Antarctic ice, or abandoned underground mines, and operated by big international collaborations. What have we learned about neutrinos in the past decade and what do we hope to uncover in the coming years? How do these large instruments work and what does it take to run large international collaborations? Why do physicists build their experiments in remote locations and what technologies do they use to detect neutrinos? What challenges do they encounter when working across continents?

We invited five leading scientists to share their excitement about neutrino physics and discuss the practical challenges they face in their research.

Speakers:
Linda Cremonesi, University College London, UK
Linda is a member of the DUNE (USA), NOvA (USA), and ANITA (Antarctica) collaborations. Linda actively engages on outreach and minority issues in STEM.

Atsuko Ichikawa, Kyoto University, Japan
Atsuko is the spokesperson of the T2K experiment (Japan). She is the recipient of the first Toshiko Yuasa prize on her contribution on the development of the J-PARC neutrino beam.

Mark Vagins, UC Irvine, USA and Kavli IPMU, Japan
Mark spent many years working on neutrino experiments in Japan and is the first full-time foreign professor at Kavli Institute for the Physics and Mathematics of the Universe (IPMU).

David Wark, University of Oxford, UK
David was the director of the particle physics group at the STFC Rutherford Appleton Laboratory and is a former T2K international spokesperson (Japan) and a former UK co-spokesperson for the SNO experiment (Canada).

Moderator:
Yoshi Uchida, Imperial College London, UK
Yoshi has been a member of various Institute of Physics committees after leading the high-energy particle physics group for many years as the chair. Yoshi is now involved in the T2K, Super-Kamiokande, and COMET (all in Japan) collaborations.

Organisers:
Teppei Katori, King's College London, Iulia Georgescu, Nature Reviews Physics
