DESCRIPTION:Speakers: Kenny KALE SAYI ()\nThe Double Chooz experiment is a
  reactor antineutrino disappearance experiment located on the site of the 
 Chooz nuclear power plant in the Ardennes region in France. The principal 
 aim of the experiment is a high precision measurement of the oscillation a
 mplitude sin2 2θ13 of the antineutrinos emitted from the two reactor core
 s of the Chooz power plant. The robustness and accuracy of this measuremen
 t depends strongly on a precise knowledge of the rates and spectral shapes
  of the backgrounds that contaminate the antineutrinos selection over the 
 neutrino oscillation expected region. We study the muon induced background
  in the Double Chooz experiment. Indeed\, cosmic muons crossing the detect
 ors or interacting in the neighborhood constitute the main source of backg
 round events encountered in Double Chooz. Dedicated identification techniq
 ues have been developed ton tag each of these backgrounds and\, consequent
 ly\, the associated spectral shapes and rates have been determined. The va
 lues obtained in our work serve as inputs in the final fit whence the θ13
  value is extracted. The latest measurement released by the Double Chooz c
 ollaboration is sin^2 θ13 = 0.119 ± 0.016.\n\nhttps://indico.tlabs.ac.za
