The researchers from the U.S. Department of Energy’s (DOE) Argonne National Laboratory and Fermi National Accelerator Laboratory have come up with a groundbreaking discovery by analyzing the data retrieved about eight years ago.
The foundations of the Booster Neutrino Experiment was laid in the year 2002. The experiment was reckoned as MiniBooNE and was undertaken at the Fermilab. It was initiated with the aim to unveil the interaction of the neutrinos with the matter. The neutrinos are incredibly light and neutral fundamental particles. The scientists have recently gone through the experimental data from the experiments conducted between the years 2009 and 2011. The experimental data revealed the first ever evidence of monoenergetic neutrinos. The mono-energetic neutrinos are those neutrinos possessing specific energy. These neutrinos are potent enough to generate a muon.
The neutrinos being extremely light in weight are influenced only by the subatomic forces. Hence, the interaction of the neutrinos with the matter is a rare fact. In lieu of their interaction, the neutrinos can travel the light years of lead before they enter into an interaction with it. The neutrinos are difficult to detect; however, their creation is relatively easy. The neutrinos are elusive, and hence the scientists have to work with the beam. Such beams are composed of a large number of the particles. The scientists shoot the beam at the location of the nuclei in a detector. The motive behind the beam shoot is a hope that the neutrinos collide successfully with the target materials.
Joe Grange says, “One complication of using these large beams is that the energies of the neutrinos are widely varied and somewhat unpredictable. This makes it difficult to interpret the data fully.”Joe Grange is an Argonne physicist and one of the geniuses who helped his fellow mates to discover the presence of mono-energetic neutrinos.
However, it is being said that the discovery about the neutrinos might help the experimentalists to overcome the difficulty in data interpretation. The scientists realized the release of the mono-energetic neutrinos from a nearby neutrino beamline at the Fermilab. In addition to their recent discovery, the scientists would co-relate the present findings with the available data of the MiniBooNE to cross-check whether any of the current neutrinos mark their presence in that MiniBooNE experiment.
The current study entitled ‘The first Measurement of Monoenergetic Muon Neutrino Charged Current Interactions’ makes its way in the Physical Review Letters.
