Measurement of semileptonic branching fractions of B mesons to narrow D** states
Using the data accumulated in 2002-2004 with the D0 detector in proton-antiproton collisions at the Fermilab Tevatron collider with a center-of-mass energy of 1.96 TeV, the branching fractions of the decays Bâ†'DÂ10(2420)Î+ÎÎX and Bâ†'DÂ2*0(2460)Î+ÎÎX and their ratio have been measured: B...
