SUMMARY:Search for active neutrino disappearance in MINOSSearch for ac
 tive neutrino disappearance in MINOS\, High Energy Seminar\, Brian Reb
 el\, FNAL
DESCRIPTION:MINOS is a long baseline neutrino oscillation experiment w
 ith two detectors<br><br>
\nseparated by a distance of 735 km.  The de
 tectors are exposed to a high<br><br>
\npower muon neutrino beam origi
 nating at Fermilab.  It has reported a<br><br>
\nsignificant deficit o
 f muon neutrinos at its far detector relative to the<br><br>
\nnear de
 tector through measurement of the rate of charged-current<br><br>
\nin
 teractions. If this deficit is due solely to conversions of muon-neutr
 inos<br><br>
\nto electron- and tau-neutrinos\, then the rate of neutr
 al-current (NC)<br><br>
\ninteractions at the far detector remains unc
 hanged from the non-oscillation<br><br>
\nprediction.  Alternatively\,
  if any muon-neutrinos convert to a sterile<br><br>
\nstate\, then the
  NC rate would be suppressed and the reconstructed energy<br><br>
\nsp
 ectrum would be distorted.  In this talk I will describe the analysis 
 of<br><br>
\nthe NC interactions from an exposure of the MINOS detecto
 rs to 3.2 x 10^20<br><br>
\nprotons on target.
