MINOS

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.

The MINOS+ collaboration at Fermilab collected data with a medium-energy neutrino beam from September 2013 to June 2016. The collaboration has exploited the data to set more stringent boundaries on the possibility of sterile neutrinos mixing with muon neutrinos.

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.

Scientists on two neutrino experiments—the MINOS experiment at Fermilab and the Daya Bay experiment in China—have presented results that limit the places where sterile neutrinos might be hiding.

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.

The 27th International Conference on Neutrino Physics and Astrophysics, commonly called Neutrino 2016, will bring together scientists from experiments around the world. Scientists working with the U.S. Department of Energy’s Fermi National Accelerator Laboratory will give numerous presentations at Neutrino 2016 and unveil some significant results.
