$D \to P ℓ^{+} ℓ^{-}$ decays assisted by QCD light-cone sum rules

Anshika Bansal, Alexander Khodjamirian, Thomas Mannel

We suggest a new method to analyse the rare $D_{(s)} \to P ℓ^{+} ℓ^{-}$ decays ( $P = I ¨ , K$ ), combining QCD light-cone sum rules (LCSR) with hadronic dispersion relations. As our main…

QCD corrections for subleading powers in $1/ m_{b}$ for the nonleptonic $b \to c c ˉ s$ transition

Thomas Mannel, Daniel Moreno, Alexei A. Pivovarov

We compute next-to-leading order QCD corrections to the $1/ m_{b}^{2}$ terms of the Heavy Quark Expansion for the contribution to inclusive nonleptonic bottom hadron decays induced by t…

Inclusive Semileptonic $b \to c ℓ I^ˉ ½$ Decays to Order $1/ m_{b}^{5}$

Thomas Mannel, Ilija S. Milutin, K. Keri Vos

Inclusive semileptonic $B \to X_{c} ℓ I^ˉ ½$ decays can be described in the Heavy Quark Expansion (HQE) and allow for a precision determination of the CKM element $∣ V_{c b} ∣$ . We ca…

Pushing the Heavy Quark Expansion for $b \to c l I^ˉ ½$ to Higher Order in $1/ m_{b}$

Ilija S. Milutin, Thomas Mannel, K. Keri Vos

The Heavy Quark Expansion (HQE) is the major tool to perform calculations for inclusive semileptonic $B \to X_{c} l I^ˉ ½$ and, consequently, for precision determinations of the CKM ma…
