Short-Distance Expansion of Heavy-Light Currents at Order 1/m

Matthias Neubert

The short-distance expansion of the heavy-light currents $q ˉ γ^{μ} Q$ and $q ˉ γ^{μ} γ_{5} Q$ is constructed to order $1/ m_{Q}$ , and to next-to-leading order in renormalization-gro…

The Subleading Isgur-Wise Form Factor $χ_{3} (v \cdot v^{'})$ to Order $α_{s}$ in QCD Sum Rules

M. Neubert, Z. Ligeti, Y. Nir

We calculate the contributions arising at order $α_{s}$ in the QCD sum rule for the spin-symmetry violating universal function $χ_{3} (v \cdot v^{'})$ , which appears at order $1/ m_{Q}$ in the…

Two-loop corrections to the Isgur-Wise function in QCD sum rules

Matthias Neubert

We complete the QCD sum rule analysis of the Isgur Wise form factor $ξ (v \cdot v^{'})$ at next-to-leading order in renormalization-group improved perturbation theory. To this end, the…
