$\bar B^0\to ϕK_S$ and $\bar K^{*0}γ$ CP Asymmetries from Supersymmetric Right-handed Flavor Mixing: Implications for Heavy Quark Phenomenology

Two recent experimental developments, when combined, may have far reaching implications. $S_{ϕK_S} < 0$, if confirmed, would imply large $s$-$b$ mixing, a new CP phase, and right-handed dynamics. Large $Δm_{B_s}$ would be likely, making the $B_s$ program at hadron machines difficult. Reconstruction of $B$ vertex from $K_S$ at B factories, as shown by BaBar's first measurement of $S_{K_Sπ^0}$, makes $S_{K_Sπ^0γ}$ in $\bar B\to \bar K^{*0}γ$ accessible. This would be a boon for B factory upgrades. Supersymmetric Abelian flavor symmetry, independently motivated, can realize all of this with a light $\widetilde{sb}_1$ squark. B factory and collider studies of flavor, CP and SUSY may not be what we had expected.
