Phenomenology of inclusive B ¯ → X s ℓ + ℓ − $$ \overline{B}\to {X}_s{\mathrm{\ell}}^{+}{\mathrm{\ell}}^{-} $$ for the Belle II era

Abstract With the first data being recorded at Belle II, we are at the brink of a new era in quark flavour physics. The many exciting new opportunities for Belle II include a full angular analysis of inclusive B ¯ → X s ℓ + ℓ − $$ \overline{B}\to {X}_s{\mathrm{\ell}}^{+}{\mathrm{\ell}}^{-} $$ which...
