heavy neutrino

1 - 2 of 2 results

One of the DUNE near detector's subdetectors, SAND, will detect neutrinos with an electronic calorimeter, which measures particle energy, and a tracker, which records particle momenta and charge. A second subdetector will use liquid argon to mimic the neutrino interactions in the far detector. The third will use gaseous argon. Working together, they will measure particles with more precision than other neutrino detectors have been able to achieve. Credit: DUNE collaboration

Particle detector at Fermilab plays crucial role in Deep Underground Neutrino Experiment

March 4, 2021

DUNE’s near detector, located at Fermilab, will take vital measurements of neutrino beam energy and composition before it reaches the experiment’s far detector in South Dakota. Its unmatched precision measurements will offer its own opportunities for the discovery of new physics.

Finding hidden neutrinos with MicroBooNE

February 13, 2020

Scientists of the Fermilab experiment MicroBooNE have published the results of a search for a type of hidden neutrino — much heavier than Standard Model neutrinos — that could be produced by Fermilab’s accelerators. These heavy neutrinos are expected to have longer travel times to the MicroBooNE detector than the ordinary neutrinos. This search is the first of its kind performed in a liquid-argon time projection chamber, a type of particle detector. MicroBooNE scientists have used their data to publish constraints on the existence of such heavy neutrinos.
