Sara Bolognesi won the 2024 CNRS silver medal

April 2, 2024

Sara Bolognesi has been awarded the 2024 silver medal of the CNRS (French National Centre for Scientific Research) in the field of nuclear and particle physics. Each year, this prestigious prize distinguishes a researcher for the originality, quality, and importance of his or her work, recognized at international level.  Dr. Bolognesi receives this award for her many contributions to particle physics. Notably, she has made enormous contributions to the T2K experiment, most recently as analysis co-coordinator and in the development and delivery of new near detectors to J-PARC for the next run period. She wishes to share this award with her fellow T2K collaborators.

A.K.Ichikawa (left), the former T2K spokesperson, won the Nishina prize in 2023 for “Constraining CP violating phase δ in neutrino oscillations“.  As stated in her citation, Ichikawa has led research in all aspects of the T2K experiment, including in the development of elements of the neutrino beamline, and her service as analysis co-coordinator and spokesperson.  She is the third recipient from T2K (T. Kobayashi and T. Nakaya in 2014.).  This prestigious award also reflects well on the hard work of the T2K collaboration as a whole, and the J-PARC accelerator team.

Kendall Mahn Elected as the new International co-spokesperson of T2K Collaboration, Replacing Federico Sanchez

November 11, 2023

The T2K collaboration has elected Kendall Mahn, a professor at Michigan State University, as its new International Co-Spokesperson, replacing Federico Sanchez from Geneva.  She has previously served in multiple roles on T2K, notably as T2K analysis co-coordinator. Kendall is excited to serve the T2K collaboration, as the collaboration makes use of the upgraded beamline, new near detectors, and upgraded far detector.

T2K physics coordinator Christophe Bronner received the Young Scientist Award of the Physical Society of Japan

October 30, 2023

He was recognized for his contributions to a recent T2K publications (Improved constraints on neutrino mixing from the T2K experiment with 3.13×1021 protons on target Phys. Rev. D 103, 112008(2021)). Christophe has made longstanding  contributions to T2K, including serving as one of the coordinators for the first joint collaborative analysis of T2K beam and SK atmospheric datasets. In addition, this award reflects the enormous work of many T2K members, and value of T2K results in the field of neutrino oscillation.

T2K Spring 2022 collaboration meeting

May 24, 2022

The T2K collaboration has recently held its first face-to-face meeting since the start of the pandemic. The meeting was held in a mixed way with two meeting centers: one at CERN (Switzerland) and another at JPARC (Japan). Even despite the split, the collaboration celebrated the possibility of resuming face-to-face discussions and meeting all the new collaborators that have joined in the last two years. The level of participation was very close to 200 collaborators, showing the strength of the experiment. The scientific results that were discussed will be public throughout the summer!

Collaborators at J-PARC made “T” and collaborators at CERN made “K”!

T2K spokespersons’ statement about the Russian Federation invasion of Ukraine

March 22, 2022

As spokespersons of the international scientific collaboration T2K, we are shocked by the Russian Federation’s brutal invasion of Ukraine and horrified by the suffering inflicted on the Ukrainian civil population. We would like to stress that the T2K experiment is built on the basis of international collaboration: the scientific successes we have achieved would not have been possible by one country working alone. We would like to offer our solidarity to all suffering directly or indirectly from these terrible events and to offer our support to the victims of this aggression and those that reject war as a way to solve human disagreements. T2K embraces science as an international endeavour and as a tool to improve human knowledge in peace and we strive to act following these human ideals.

Prof. Chang Kee Jung Wins American Physical Society’s 2022 Julius Edgar Lilienfeld Prize

December 27, 2021

Chang Kee Jung distinguished professor, the chair of the Department of Physics and Astronomy at Stony Brook University, and a former co-spokesperson of T2K has been selected to receive the American Physical Society’s 2022 Julius Edgar Lilienfeld Prize for his outstanding contributions and leadership in experimental neutrino physics, and for outstanding teaching and outreach, especially on the physics of sports. Prof. Jung founded the Neutrino and Nucleon Decay group at Stony Brook University in the 1990s and since then has played important roles in the neutrino experiments in Japan, such as SK, K2K and T2K.

Dr. Sara Bolognesi won the EPS Emmy Noether Distinction for Women in Physics

September 14, 2021

Dr. Sara Bolognesi has been awarded the Summer 2021 Emmy Noether Distinction of the European Physical Society “For her development of the data analysis techniques that conclusively improved the sensitivity of the CERN-CMS experiment, thus allowing the discovery of the Higgs boson and the first measurement of its spin and parity.” Dr. Sara Bolognesi is member of the Institut de Recherche sur les lois Fondamentales de l’Univers – Institute of Research on the Fundamental laws of the Universe of the CEA (IRFU) – Commissariat aux Energies Atomiques et Alternatives (CEA), Saclay, France. 

Dr. Sara Bolognesi joined the T2K experiment in 2013 making instrumental contributions that lead to the first indication of possible CP violation in leptons in 2020. Dr. Sara Bolognesi is now the physics coordinator of the experiment.
