Sum rules for light-by-light scattering
Vladimir Pascalutsa, Marc Vanderhaeghen
We derive a set of sum rules for the light-by-light scattering and fusion: , and verify them in lowest order QED calculations. A prominent implication of these sum rules…

Towards Precision B-physics from Non-Perturbative Heavy Quark Effective Theory
Michele Della Morte, Jochen Heitger
We convey an idea of the significant recent progress, which opens up good perspectives for high-precision ab-initio computations in heavy flavour physics based on lattice QCD. Rath…
