From PBS Space Time, Jan. 6, 2020: Why is there something rather than nothing? The answer may be found in the weakest particle in the universe: the neutrino. In this 10-minute video, PBS Space Time host Matt O’Dowd and Fermilab scientist Don Lincoln explore the mysteries of the neutrino and how Fermilab is tackling them. The elusive neutrino may hold powerful secrets, from the unification of the forces of nature to the biggest question of all: Why is there something rather than nothing?
In his doctoral thesis, Todd details a method for data analysis in a way that minimizes a source of bias in some particle physics experiments. By analyzing information from two distant detectors simultaneously rather than sequentially, he incorporated the lack of precision knowledge in both detectors. A University of Cincinnati graduate, Todd used data from Fermilab’s MINOS and MINOS+ experiments, and his analysis can be applied in other neutrino research as well.
From CERN Courier, March 8, 2019: Newly published results from the MINOS+ experiment at Fermilab cast fresh doubts on the existence of the sterile neutrino — a hypothetical fourth neutrino flavor that would constitute physics beyond the Standard Model. MINOS+ studies how muon neutrinos oscillate into other neutrino flavors as a function of distance travelled.
Physicists often find thrifty, ingenious ways to reuse equipment and resources. What do you do about an 800-ton magnet originally used to discover new particles? Send it off on a months-long journey via truck, train and ship halfway across the world to detect oscillating particles called neutrinos, of course. It’s all part of the vast recycling network of the physics community.
From Physics, July 26, 2016: A team at MIT analyzes data from Fermilab’s MINOS neutrino experiment. The results rule out a class of realist models in which the evolving system does not depend on any “memory” of its initial state.
From Motherboard, July 20, 2016: A team of MIT physicists has observed quantum correlations extending 456 miles from Fermilab’s MINOS experiment near Chicago to an underground detector in Minnesota.
