| dc.description | The baryon asymmetry of the Universe requires CP violation, but the Standard Model falls short by a factor of $10^{-10}$ or more. Starting from a clue at the $B$ factories, we point out that the large Yukawa couplings of the sequential fourth generation $t^\prime$ and $b^\prime$ quarks can provide enhancement by a factor of over $10^{13}$, making the 2-3-4 generation quark sector a viable source of CP violation for the baryon asymmetry of the Universe. With recent hints of large $\sin2Φ_{B_s}$ in $B_s^0$-$\bar B_s^0$ mixing from the Tevatron, the ultimate test would be to discover the $t^\prime$ and $b^\prime$ quarks at the Large Hadron Collider. | |
