Description
The DUNE experiment is hosted by Fermi National Accelerator Laboratory at Chicago, IL, USA, the largest particle physics and accelerator laboratory in the United States. The DUNE experiment will send an intense neutrino beam 1300 kilometers through the earth from Fermilab to South Dakota. There, about 1.5 kilometers underground, a gigantic 70 kT liquid-argon neutrino detector, will analyze how those neutrinos behave and interact, studying neutrino oscillations between muon and electron neutrinos and will attempt to answer fundamental questions in particle physics, such as CP symmetry, proton decay, and more.
The ProtoDUNE-SP is a prototype of the DUNE far detector and is a 7,2 x 6,9 x 6-meter tank containing about 800 tonnes of liquid argon. This prototype detector is located at the CERN laboratory, in Geneva, Switzerland, where it has been exposed to beams of electrons, pions, muons, and cosmic particles. Cosmic muons are a “standard candle” and all underground, or surface, detectors use those for time stability and reconstruction studies, but also physics measurements.
We will describe and report preliminary results on the measurement of the cosmic muon seasonal variation with the ProDUNE-SP detector, using a state-of-the-art particle flow reconstruction method PandoraPFA.
