M Theory Lesson 332

If we vary $b$ over a large positive range, while keeping $a$ and $c$ at their CKM values, the CP phase $2 \beta_s$ varies over all angles $\in \{ 0, - \pi \}$, slowly approaching $- \pi$ for very large $b$. This variation does not greatly alter the five large CKM entries, or the entry corresponding to $c$, but it does move the probability matrix well away from current experimental bounds. At small $b$, the phase $2 \beta_s$ (called phi on the graph) goes like $2abc$.
