Toward a complete description of b → uℓ − ν ¯ $$ \overline{\nu} $$ within the Weak Effective Theory decays

Abstract We fit the available data on exclusive semileptonic b → uℓ − ν ¯ $$ \overline{\nu} $$ decays within the Standard Model and in the Weak Effective Theory. Assuming Standard Model dynamics, we find V ub = 3.59 − 0.12 + 0.13 × 10 − 3 $$ \left|{V}_{ub}\right|={3.59}_{-0.12}^{+0.13}\times {10}^{-...
