Status ofV ub measurement with BELLE detector
Semileptonic decays ofB →X u lv have great importance both from theoretical and experimental point of view, as they are useful for extracting the magnitude ofV ub, one of the tiniest elements of CKM matrix. Similarly measurement ofB √ Ds×u can be used to calculateV ub The Belle Collaboration has measured these branching ratios and extractedV ub for various theoretical models.
