| Title: |
CP Violation for the Heaven and the Earth
![[PDF]](/img/common/point04.gif) |
| Abstract: |
The baryon asymmetry of the Universe requires CP violation, but
the
Standard Model falls short by a factor of 10-10 or more. We point out that
the large
Yukawa couplings of a sequential fourth generation of quarks can enhance the
Jarlskog
invariant by a factor of over 1013, making the 2-3-4 generation quark
sector a viable source
of CP violation for the baryon asymmetry of the Universe. Our observation
started from a
clue at the B factories, which anticipated the recent hint of large
sin2beta_s in B_s -> J/psi
phi mode from the Tevatron. The ultimate test would be to discover the t'
and b' quarks at
the Large Hadron Collider, which would also be touched upon. If so, in a few
years we could
uncover on Earth, the CPV relevant for the Heavens.
