Symmetries in B → D ∗ ℓν angular observables
Abstract We apply the formalism of amplitude symmetries to the angular distribution of the decays B → D ∗ ℓν for ℓ = e, μ, τ . We show that the angular observables used to describe the distribution of this class of decays are not independent in absence of New Physics contributing to tensor operators...
