Scientists at Fermi National Accelerator Laboratory have observed the first neutrino interactions in the Short-Baseline Near Detector (SBND), marking a significant milestone in their efforts to explore neutrino oscillations and search for a potential fourth neutrino flavor that could challenge the Standard Model of particle physics. Phys.org reports: SBND is the final element that completes Fermilab’s Short-Baseline Neutrino (SBN) Program and will play a critical role in solving a decades-old mystery in particle physics. Getting SBND to this point has been an international effort. The detector was built by an international collaboration of 250 physicists and engineers from Brazil, Spain, Switzerland, the United Kingdom and the United States. […] The Short Baseline Neutrino Program at Fermilab will perform searches for neutrino oscillation and look for evidence that could point to this fourth neutrino. SBND is the near detector for the Short Baseline Neutrino Program while ICARUS, which started collecting data in 2021, is the far detector. A third detector called MicroBooNE finished recording particle collisions with the same neutrino beamline that same year.
The Short Baseline Neutrino Program at Fermilab differs from previous short-baseline measurements with accelerator-made neutrinos because it features both a near detector and far detector. SBND will measure the neutrinos as they were produced in the Fermilab beam and ICARUS will measure the neutrinos after they’ve potentially oscillated. So, where previous experiments had to make assumptions about the original composition of the neutrino beam, the SBN Program will definitively know. “Understanding the anomalies seen by previous experiments has been a major goal in the field for the last 25 years,” said Schmitz. “Together SBND and ICARUS will have outstanding ability to test the existence of these new neutrinos.”
