QED corrections in B ¯ → K ¯ ℓ + ℓ − $$ \overline{B}\to \overline{K}{\mathrm{\ell}}^{+}{\mathrm{\ell}}^{-} $$ at the double-differential level

Abstract We present a detailed analysis of QED corrections to B ¯ → K ¯ ℓ + ℓ − $$ \overline{B}\to \overline{K}{\mathrm{\ell}}^{+}{\mathrm{\ell}}^{-} $$ decays at the double-differential level. Cancellations of soft and collinear divergences are demonstrated analytically using the phase space slicin...
