Weak annihilation contribution to angular observables in $$B_{c}^+\rightarrow D^{*+}\ell ^{+}\ell ^{-}$$ B c + → D ∗ + ℓ + ℓ - decays
Abstract We analyze the rare semileptonic decays $$B_{c}^+ \rightarrow D^{*+}(\rightarrow P_1 P_2)\ell ^{+}\ell ^{-}$$ B c + → D ∗ + ( → P 1 P 2 ) ℓ + ℓ - , with $$P_1 P_2 = D^+ \pi ^0$$ P 1 P 2 = D + π 0 or $$D^0 \pi ^+$$ D 0 π + , and $$\ell =\mu , \tau $$ ℓ = μ , τ . We focus on the impact of wea...
