Jon Butterworth has written a book about being involved in the discovery of the Higgs boson, Smashing Physics, available here, and in North America as “Most Wanted Particle”.
Nova can measure the difference, and as it collects more and more data it will tell us more about the mixing and the nature of the neutrino, a particle which is one of the most abundant in the universe and which may hold clues to some of the big puzzles which remain open in physics.Īs will higher-energy collisions at the LHC, when they happen. However, as they travel the 800 or so kilometres to the far detector, the neutrinos undergo quantum mixing, and can arrive there as, for example, electron neutrinos, meaning they can produce an electron when they interact instead of a muon. Most of the neutrinos coming from pion decays are “muon neutrinos”, which means that when they hit some matter (for example the near or far detector) they should produce muons, a fairly short lived particle very like the electron but heavier. Neutrinos are always created by a decay or some other interaction which involves the weak force (the fundamental force carried by W and Z bosons). The main injector used to provide protons and antiprotons for the Tevatron, the highest energy particle collider in the world before the LHC took over. The beam is called NUMI, for “neutrinos at the main injector”, and it supplies some other experiments with neutrinos too. The beam of neutrinos is created by firing protons from “main injector” into a target of carbon, and focussing the resultant particles (pions) before they decay into neutrinos. Nova has one detector (the near one) at Fermilab, and another (the far one) over 800 km away. The Nova experiment detects neutrinos created at the Fermi National Accelerator laboratory in Chicago. We present the efficiency for detecting the neutrino signal depending on the supernova model and the distance to the progenitor star.I don’t think much of this is neutrinos, but it’s pretty Photograph: Nova/Fermilab Studying these neutrinos can provide information about the processes affecting the supernova explosion, probe existing supernova models, and in comparison to other neutrino experiments with different sensitivities, could answer questions about the neutrino properties as the neutrinos transit both the protoneutron star and the empty space on their way to Earth. NOvA experiment is designed to measure neutrino oscillations in a νμ beam with average energy of 2 GeV and has little overburden, detecting interacting neutrinos with tens of MeV energy from a supernova requires dedicated data selection and background reduction. THE OPTICAL OBSERVATIONS OF X RAY NOVA GS2023 + 33 V404 CYG c89 O. We present the efficiency for detecting the neutrino signal depending on the supernova model and the distance to the progenitor star.ĪB - This work describes a data-driven trigger designed to detect neutrino signal from a galactic supernova using the NOvA detectors. Therefore the cross section of neutrino scattering by nucleus in the collapsing. Seen in 1963, this neutrino detector, located 2,300 feet down in a limestone. NOvA experiment is designed to measure neutrino oscillations in a νμ beam with average energy of 2 GeV and has little overburden, detecting interacting neutrinos with tens of MeV energy from a supernova requires dedicated data selection and background reduction. About 100 billion solar neutrinos pass through your thumbnail every second, says Bahcall, and you never notice a thing.
