Title: Branching Fraction and CP Asymmetry Measurements in Inclusive B → Xs ℓ⁺ℓ⁻ and B → Xsγ Decays from BABAR

We present an update on total and partial branching fractions and on CP asymmetries in the semi-inclusive decay B → Xsℓ⁺ℓ-. Further, we summarize our results on branching fractions and CP asymmetries for semi-inclusive and fully-inclusive B → Xsγ decays. We present the first result on the CP asymmetry difference of charged and neutral B → Xsγ decays yielding the first constraint on the ratio of Wilson coefficients Im(C8eff/C7eff).
