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.
\n
\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.
