B →ππ form factors from light-cone sum rules with B-meson distribution amplitudes

Abstract We study B → ππ form factors using QCD light-cone sum rules with B-meson distribution amplitudes. These form factors describe the semileptonic decay B → π π ℓ ν ¯ ℓ $$ B\to \pi \pi \ell {\overline{\nu}}_{\ell } $$ , and constitute an essential input in B → ππℓ + ℓ − and B → πππ decays. We e...
