Chapter 6. Conclusion
This is the time to mention some developments of the considered
model. The idea to give VEVs at the top and bottom elements of
χ triplet was given in Ref. [114]. Some consequences such as the
atomic parity violation, Z − Z
0 mixing angle and Z
0 mass were
studied [24]. However, in the above-mentioned works, the W − Y
and W4, Z, Z0 mixings were excluded. To solve the difficulties such
as the standard model coupling ZZh or quark masses, the third
scalar triplet was introduced. Thus, the scalar sector did not to be
minimal anymore and the economical was though to be unrealistic!
