Overview & Topics


September, 6th-11th, 2021


THotel, Cagliari (Italy) and online

NuFACT 2021 is the twentysecond in the series of yearly international workshops which started in 1999 and which had previously been called the International Workshop on Neutrino Factories. The change of name to International Workshop on Neutrinos from Accelerators is related to the fact that the workshop program has, over the years, come to include all current and future accelerator and also reactor based neutrino projects, including also muon projects, not only the Neutrino Factory project.

The main goal of the workshop is to review the progress of current and future facilities able to improve on measurements of the properties of neutral and charged lepton flavor violation, as well as searches for new phenomena beyond the capabilities of presently planned experiments. The workshop is both interdisciplinary and inter-regional in that experimenters, theorists and accelerator physicists from Asia, the Americas and Europe share expertise with the common goal of reviewing the results of currently operating experiments and designing the next generation of experiments.

The NuFACT 2021 workshop is divided into six Working Groups covering the following topics:

  1. Neutrino Oscillation Physics (Working Group 1),
  2. Neutrino Scattering Physics (Working Group 2),
  3. Accelerator Physics (Working Group 3),
  4. Muon Physics (Working Group 4), and
  5. Neutrinos Beyond PMNS (Working Group 5)
  6. Detectors (Working Group 6)
Moreover, there will be a special session on Diversity, Education and Outreach.

For the 2021 edition, to comply with the different situation in the various countries concerning  vaccines and travel regulations, we will hold the conference in mixed mode: the participants and speakers having the opportunity to travel to Italy may attend the conference in person, while the others may attend and give their talks remotely.

To make it possible for an (almost) worldwide online broadcasting, the conference plenary and parallel sessions will be from 12.40 to 17.30 Italy summer time CEST. Compared to the last edition, all plenaries and parallel sessions were maintained, with the addition of WG6, dedicated to detector developments.

To profit from the conference room availability, there will also be satellite workshops running on Italian mornings, nu-Storm/ENUBET, ESS-nu, and a dedicated diversity, outreach & education session.

We will also hold an online poster session in a virtual room.
