Neutrino mass matrix with no adjustable parameters
On the basis of the so-called “yukawaon” model, we found a special form of the neutrino mass matrix M ν which gives reasonable predictions. The M ν is given by a multiplication form made of charged lepton mass matrix M e and up-quark mass matrix M u . This M ν has no adjustable parameters except for...

Zusammenfassung: | On the basis of the so-called “yukawaon” model, we found a special form of the neutrino mass matrix
M
ν
which gives reasonable predictions. The
M
ν
is given by a multiplication form made of charged lepton mass matrix
M
e
and up-quark mass matrix
M
u
. This
M
ν
has no adjustable parameters except for those in
M
e
and
M
u
. Here,
M
e
and
M
u
are described by one parameter
a
e
(real) and two parameters
a
u
(complex), respectively, and those parameters are constrained by their observed mass ratios. With this form of
M
ν
, in spite of having only three parameters, the
M
ν
can give reasonable predictions: sin
