|講演タイトル||Matter Effect from Non-Standard Interactions of the Neutrino|
|講演者||竹内 建氏(Virginia Tech)|
Abstract: Neutrino oscillation in matter is sensitive to interactions
between the neutrinos and the matter particles, including
the Standard Model W-exchange interaction and any
Non-Standard Interactions (NSI's) that the neutrinos may have.
In this talk, I will show how the Jacobi method can be
utilized to find analytical expressions for the effective
mixing angles and effective CP violating phase of the
neutrinos in matter, which lead to extremely simple and
compact expressions for the oscillation probabilities.
All matter effects can be absorbed into the "running" of
the effective parameters. It will be shown that the SM
interactions cause theta12 and theta13 to run, while NSI's
involving the mu and tau neutrinos cause theta23 and delta
to run. By looking at the "running" of the effective
parameters, it is possible to find the best conditions
under which the NSI effects will be manifest.
