Description
Semileptonic B meson decays, B ➞ X l ν, are currently the preferred modes for determining the Cabibbo-Kobayashi-Maskawa (CKM) matrix elements |Vcb| and |Vub|, two fundamental parameters of the Standard Model. At the same time they can also be used to test and refine the theoretical tools used for describing B mesons and their decays. Based on the large data sample accumulated by the Belle experiment at the KEKB asymmetric energy e+ e- collider at KEK, Japan, we present new results on semileptonic B and Bs meson decays.
