The LSND Experiment and the Zee Model
A recent experiment LSND at Los Alamos has provided\cite{1} an indication of
oscillations with of
order 1ev or greater and between and . Such a value of for
oscillations was not expected in the standard see-saw model\cite{2} suggested
by SO(10) with a large mass hierarchy because it leads to too large a value of
to fit cosmological constraints. Furthermore within that model
the LSND result is inconsistent with the indications of oscillations from both
atmospheric neutrinos\cite{3} and solar neutrinos.\cite{4}Comment: 3 pages, latex, no figure
Strong Phases in the Decays B to pi pi
Two sources of strong phases in the decays to are identified:
(1) "quasi-elastic scattering" corresponding to intermediate states like
and , (2) ``'' corresponding to intermediate
states like and . Possibilities of using data to
identify these two sources are discussed and illustrated. Present data suggests
both sources may be significant.Comment: 6 pages, 1 figure
CP Violation in Mixing
The existence of mixing at a detectable level requires
new physics, which effectively yields a superweak interaction.
In general this interaction may involve significant CP violation. For small
values of the mixing it may be much easier to detect the CP-violating part of
the mixing than the CP-conserving part.Comment: 3 pages, latex, no figure
