Symmetry-Breaking Effects on Form Factors and Observables in $B \to K_{0}^{*} (1430) μ^{+} μ^{-}$ Decay

Saba Ayub, Saba Shafaq, Arslan Sikandar +1

In the heavy-quark and large-energy limits, symmetry relations reduce the number of independent form factors governing heavy-to-light $B$ -meson decays. Exploiting these relations,…
