SUMMARY:Three flavour neutrino oscillations with MINOS and CHIPS\, NPA
 C (Nuclear/Particle/Astro/Cosmo) Forum\, Andy Perch\, University Colle
 ge London
DESCRIPTION:Neutrinos created in one flavour state (electron\, muon\, 
 and tau) can oscillate into a different one as they propagate.  Such o
 scillations imply that states of a given flavour are really superposit
 ions of three mass states\, with the rate of oscillations depending on
  the difference in squared masses of these states.  These differences 
 have two characteristic scales\, one measurable with solar neutrinos\,
  and one with neutrinos from atmospheric and accelerator sources\, so 
 early experiments assumed mixing between only two flavours.<br>
\n<br>
 
\nWith larger and more precise detectors the full three-flavour struc
 ture can to begin to be probed.  The mass ordering of the three states
  is accessible via neutrino interactions with matter as they propagate
  through the Earth\, whilst the possibility that neutrino oscillations
  violate charge parity symmetry can be probed via electron neutrino ap
 pearance in a muon neutrino beam.  In this talk I will discuss an upda
 te to the MINOS atmospheric neutrino analysis\, and discuss CHIPS: an 
 R&D experiment aiming to build a large water Cherenkov detector in a f
 looded mine pit in Northern Minnesota\, which deployed a small prototy
 pe in the summer of 2014.
