Perturbative and non-perturbative QCD corrections to wide-angle Compton scattering

The paper contains a sign mistake. In Eqs. (1), (25), (30) and (38) the form factor R T and the ratio \(\kappa\) are to be replaced by -R T and \(-\kappa\), respectively. The predictions for A LL = K LL shown in Fig. 7, are nearly independent of this change while those for A LS = - K LS are substantially smaller in absolute value than the results shown in Fig. 8. All other results ...

Generalized parton distributions in impact parameter space

The kinematical factor in the positivity bound (36) is incorrect. The bound correctly reads \(\begin{array}{lll} &&(1-\xi^2)^3\, \Big|\, {\cal I}_{\lambda'\lambda}(x,\xi,\vec{b}) \,\Big|^2 \\ && \le {\cal I}_{++}\Big(\frac{x-\xi}{1-\xi},0, \frac{\vec{b}}{1-\xi}\Big)\; {\cal I}_{++}\Big(\frac{x+\xi}{1+\xi},0, \frac{\vec{b}}{1+\xi}\Big) . \end{array}\) Our corrected result agrees ...
