Abstract

A mini-review of measurements of inclusive semileptonic B → X_cℓν and radiative B→ X_sγ decays is presented. The semileptonic X_c mass moments are presented from Belle and BABAR. The inclusive B→ X_sγ gamma branching fraction is presented from Belle as well as a preliminary measurement of the direct CP-asymmetry of B → X_s+dγ decays at BABAR. Fundamental Standard Model parameters and heavy quark parameters can be derived from the X_c mass and lepton energy moments from B → X_cℓν decays and from the photon energy moments from B → X_sγ decays. The values of the CKM matrix element |V_cb|, the b-quark mass m_b, and the Fermi motion of the b-quark inside the B-meson are presented based on a global fit to these moments by the Heavy Flavor Averaging Group.
