DESCRIPTION:We solve neutrino mysteries by watching them interact with our
  detectors\; most of the time\, they do not even shake hands though. But w
 hen they do\, the neutrino can acquire an electric charge and knock things
  out of the nucleus as it escapes – leaving a crime scene behind. The tr
 aces of the charged lepton and the knock-out are collected by the detector
 \, and it is our job to identify and count the original neutrinos. So far\
 , this has not been an easy task: nuclear effects have obscured much of th
 e evidence of the intruding neutrinos\, leaving us complex and seemingly i
 rrelevant information. Not all neutrinos misbehave but\, unfortunately\, t
 he neutrinos we care about – those which could possibly tell us about th
 e creation of the cosmos – all have this _modus operandi_. To reconstruc
 t the resulting crime scene\, we therefore need a complete understanding o
 f how the nuclear effects work.\nBoth the charged lepton and the knock-out
  have partial fingerprints from the original neutrino\, which lie ambiguou
 sly on top of the nuclear effect background. It has been found that these 
 fingerprints can be removed via a novel neutrino CSI technique known as 
 ‘final-state correlations’. \nIn our recent MINERvA neutrino investiga
 tion\, this new technique was used and a detailed reconstruction of the nu
 clear effects was presented. The underlying phenomena – such as the init
 ial state of the nucleus\, additional knock-out mechanism\, and final-stat
 e interactions between the knock-out and the rest of the nucleus – are n
 ow separated. In this seminar\, the current status and future prospects of
  nuCSI will be discussed.
