[T]he new MINOS study significantly reduces the systematic errors of its earlier work with detailed measurements of the behavior of the experiment's GPS timing system, improved understanding of the delays of electronic components at every stage of the MINOS detectors and the use of upgraded timing equipment, designed and implemented with the assistance of the National Institute of Science and Technology and the United States Naval Observatory.

 

Applying these improved understandings, the MINOS collaboration measures a neutrino arrival time for travel between Fermilab and Soudan, Minn., that is consistent with the expected travel time at the speed of light. The difference between the measured and calculated times is -15 ± 31 nanoseconds, indicating no observable effect.
