Two-Loop Renormalization of Heavy--Light Currents at Order 1/m_Q in the Heavy-Quark Expansion
Thomas Becher, Matthias Neubert, Alexey A. Petrov
We present exact results, at next-to-leading order in renormalization-group improved perturbation theory, for the Wilson coefficients appearing at order 1/m_Q in the heavy-quark ex…

Lorentz Invariant Baryon CHPT
T. Becher
Using the example of the elastic -amplitude, we discuss the low energy expansion of QCD amplitudes in the sector with baryon number one. We show that the chiral expansion of th…
