Download or read book Review of Exculsive B to D(*, **)Lnu Decays written by and published by . This book was released on 2007 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper reviews semileptonic decays of B-mesons to states containing charm mesons, i.e., D, D*, D** and possible non-resonant D{sup (*)}[eta][pi] states as well. The paper covers measurement of branching fractions, form-factors and, most importantly, the magnitude of the CKM matrix element V{sub cb}. I will not attempt a comprehensive review, but will concentrate on reasonably fresh results and consider mostly exclusive measurements. I will also comment on the consistency of the results and what needs to be done to resolve the apparent conflicts.
