b → c semileptonic sum rule: current status and prospects
Abstract The b → c semileptonic sum rules provide relations between the decay rates of $$B\to {D}^{(*)}\tau \overline{\nu }$$ and $${\Lambda }_{b}\to {\Lambda }_{c}\tau \overline{\nu }$$ . Starting from the heavy quark and zero-recoil limits, we revisit the derivation of the sum rule for total decay...
