First measurement of the ratio of branching fractions B(Λb 0→Λc+μ-ν̄μ)/B(Λb 0→Λc+π-)

This article presents the first measurement of the ratio of branching fractions B(Λb0→Λc+μ-ν̄μ)/ B(Λb0→Λc+π-). Measurements in two control samples using the same technique B(B̄0→D+μ- ν̄μ)/B(B̄0→D+π-) and B(B̄ 0→D*(2010)+μ-ν̄μ)/ B(B̄0→D*(2010)+π-) are also reported. The analysis uses data from an int...
