New results from the T2K experiment in Japan rule out with 99.7% confidence nearly half of the possible range of values that could indicate how neutrinos behave compared to their antimatter counterparts.
From Nature, April 15, 2020: In a mirror world, antiparticles should behave in the same way as particles. But it emerges that neutrinos, electrons and their more exotic cousins might not obey this expected pattern. Fermilab scientist Jessica Turner and Durham University scientist Silvia Pascoli provide a commentary on T2K’s recent neutrino result, CP violation, and how other neutrino experiments, including the international Deep Underground Neutrino Experiment, hosted by Fermilab, will make more precise measurements of the mysterious neutrino’s behavior.
From The New York Times, April 15, 2020: An international team of 500 physicists from 12 countries, known as the T2K collaboration, reported that they had measured a slight but telling difference between neutrinos and their opposites, antineutrinos. Fermilab Deputy Director Joe Lykken comments on the result and how the international Deep Underground Neutrino Experiment, hosted by Fermilab, may be able to make a definitive discovery of CP violation.
When scientists begin taking data with the Deep Underground Neutrino Experiment in the mid-2020s, they’ll be able to peer 13.8 billion years into the past and address one of the biggest unanswered questions in physics: Why is there more matter than antimatter? To do this, they’ll send a beam of neutrinos on an 800-mile journey from Fermilab to Sanford Underground Research Facility in South Dakota. To detect neutrinos, researchers at several DOE national laboratories, including Fermilab, are developing integrated electronic circuitry that can operate in DUNE’s detectors — at temperatures around minus 200 degrees Celsius. They plan to submit their designs this summer.
From Event Horizon podcast, March 19, 2020: Fermilab scientist James Annis and John Michael Godier discuss neutrinos, dark energy, dark matter and upcoming cosmological surveys in this 30-minute interview.
From March 6, 2020: Durante a 5ª Comista, os dois países adotaram um Plano de Trabalho em Ciência e Tecnologia para o período de 2020 a 2023, que estabelece as prioridades comuns descritas acima. Também foram firmados acordos de cooperação na área de cooperação científica em Física de Partículas de Alta Energia entre o Fermilab (Laboratório de pesquisa científica do Departamento de Energia dos EUA) e a FAPESP e outro acordo na mesma área entre o Fermilab e a UNICAMP.
From the Brazil Ministry of Science, Technology, Innovation and Communication, March 6, 2020: Comissão mista entre os dois países possui grupos de trabalho para pesquisas sobre temas como saúde, espaço, tecnologias e agências de financiamentos.
From Brazilian Space, March 10, 2020: Durante a 5ª Comista, os dois países adotaram um Plano de Trabalho em Ciência e Tecnologia para o período de 2020 a 2023. Também foram firmados acordos de cooperação na área de cooperação científica em Física de Partículas de Alta Energia entre o Fermilab e a Fundação de Amparo à Pesquisa do Estado de São Paulo e outro acordo na mesma área entre o Fermilab e a Universidade de Campinas.
The groundbreaking ANNIE experiment at Fermilab has seen its first neutrino events. This milestone heralds the start of an ambitious program in neutrino physics and detector technology development. It is also a cause for celebration by the international ANNIE collaboration, composed of groups from Germany, the United Kingdom and the United States.
Scientists have begun filling the ICARUS detector at Fermilab with liquid argon, moving one step closer toward neutrino oscillation measurements and the potential discovery of sterile neutrinos.
