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