Abstract

In this article, we review five new Belle measurements relevant to the CKM matrix elements |V _cb | and |V _ub |: one measurement of inclusive B→ X _c l ν decays using full reconstruction of the other B, three different measurements of inclusive B→ X _u l ν decays using various experimental techniques, and finally the first evidence for the decay B ⁺→ω l ⁺ ν.
