Combined exclusive Vub and Vcb

LHCb published a measurement of |Vub/Vcb| from the partial rate for Λb→pμν normalized to Λb→Λcμν, [arXiv:1504.01568].
The published value, |Vub/Vcb|=0.083+-0.004exp.+-0.004th. updated to the HFAG average result for the Branching Fraction BF(Λc→p K π)=(6.46 +- 0.24)%, is


The result of a combined fit using as input only the exclusive |Vcb| and |Vub| measurements, with the |Vub/Vcb| measurement gives the following results

|Vub|=(3.50 +- 0.13)x10-3
|Vcb|=(39.13 +- 0.59)x10-3

the correlation is ρ=0.14, with a fit P(χ2)=11.0%. In this combination the uncertainties are considered uncorrelated.
