|Vub| determination usingB→ π form factor from light-cone sum rule

Name: Work Video:
Duration: 3 min 30 s
Description: A determination of |Vub| from the exclusive semileptonic B → πlvl decay is presented, using the new calculation of the B → π form factor fB+π(0) from QCD light-cone sum rule with O(αs) accuracy in twist-2 and twist-3 terms and employing the MS scheme for the b-quark mass.
