Abstract We study the inclusive and exclusive cross sections of $$e^+e^-\rightarrow \text {hadrons}$$ e + e - → hadrons for center-of-mass energies between 3.70 and $$3.83\,\,\textrm{GeV} $$ 3.83 GeV to infer the mass, width, and couplings of the $

Using dispersive methods, we study the B→γ* form factors underlying the decay B−→ℓ−ν¯ℓℓ′−ℓ′+. We discuss the ambiguity that arises from a separation of the full B−→ℓ−ν¯ℓℓ′−ℓ′+ amplitude into a hadronic t
