Distribution Amplitudes – a Reprise
We review the status of the leptonic decay constants f K and f ,⊥ K of the K and K * , respectively , and the SU(3) breaking quantities a 1 (K) and a ,⊥ 1 (K *), the first Gegenbauer-moments of the leading-twist distribution amplitudes of K and K *. We obtain new predictions from QCD sum rules which are relevant for the calculation of K and K * form factors, for instance T B→K * 1 , which deter...
متن کاملPion-Nucleon Distribution Amplitudes
In recent years there has been increasing attention to hard exclusive processes involving emission of soft pions in the final state. In the near future new experimental data will emerge and their interpretation requires information about the nucleon wave function. Such processes are attractive as they provide us new insights in the hadron (nucleon) structure. At this point the nucleon distribut...
متن کاملPhoton Distribution Amplitudes in QCD
We develop a consistent technique for the calculation of real photon emission in hard exclusive processes, which is based on the background field formalism and allows a convenient separation of hard electromagnetic and soft hadronic components of the photon. The latter ones are related to matrix-elements of light-cone operators in the electromagnetic background field and can be parametrized in ...
متن کاملRenormalization of B-meson distribution amplitudes
We summarize recent calculations concerning the evolution kernels of the two-particle B-meson distribution amplitudes φ + and φ − taking into account three-particle contributions, as well as the evolution kernel of the combination of three-particle distribution amplitudes Ψ A − Ψ V. We exploit these results to confirm constraints on φ + and φ − derived from the light-quark equation of motion.
متن کاملImpact Representation of Generalized Distribution Amplitudes
We develop an impact representation for the generalized distribution amplitude which describes the exclusive hadronization of a quark-antiquark pair to a pair of mesons. Experiments such as γγ → ππ and γN → ππN ′ are shown to probe the transverse size of the hadronization region of the quark antiquark pair that one can interpret as the transverse overlap of the two emerging mesons. An astonishi...
