QCD Sum Rules for Heavy Flavors
I give a short summary of QCD sum rule results for hadrons involving a heavy quark, with emphasis on recent developments.
This is a short review of the theory and phenomenology of baryon distribution amplitudes, including recent applications to the studies of nucleon form factors at intermediate momentum transfers usingExpand
Light cone sum rules for the nucleon form-factors
We argue that soft non-factorisable terms give a significant contribution to the baryon form factors at intermediate momentum transfers and set up a framework for the calculation of such terms in theExpand
Investigation of the semileptonic weak decays of B(s) to S (Scalar Meson) via light-cone QCD sum rules
In this paper, the semileptonic weak decay process of B (s) → S scalar mesons is investigated by using the light-cone QCD sum rules (LCSR) in the nonperturbative part. The corresponding transitionExpand
QCD sum rules for the coupling constants of vector mesons to octet baryons
The QCD sum rules on the light cone proposed by Wang for the coupling constants of the ρ meson are generalized to the vector mesons ω and φ and all octet baryons, the Λ-hyperon included. A comparisonExpand
Exclusive Nonleptonic B Decays from QCD Light-Cone Sum Rules
We are going to review recent advances in the theory of exclusive nonleptonic B decays. The emphasis is going to be on the factorization hypothesis and the role of nonfactorizable contributions forExpand
Improved light-cone sum rules for the electromagnetic form factors of the nucleon
We calculate the electromagnetic form factors of the nucleon within the light-cone sum rule approach. In comparison to previous work [Phys. Rev. D 65 (2002) 074011] we suggest to use a pureExpand
Three-particle contributions to the renormalisation of B-meson light-cone distribution amplitudes
We study light-cone distribution amplitudes of heavy-light systems, such as a B-meson. By an explicit computation, we determine how two-parton distribution amplitudes mix with three-parton ones atExpand
Investigation of gf0ργ and ga0ργ coupling constants in light cone sum rules
We present a calculation of the coupling constant of f0→ργ and a0→ργ decays from the point of view of the light cone QCD sum rules. We estimate the coupling constants gf0ργ, which are an essentialExpand
Light cone sum rules for gamma* N ---> Delta transition form-factors
A theoretical framework is suggested for the calculation of {gamma}* N {yields} {Delta} transition form factors using the light-cone sum rule approach. Leading-order sum rules are derived andExpand


Perturbative Quantum Chromodynamics
From the perspective of the hadronic physics of a decade ago it seems incredible that there now exists a viable, fundamental theory of the strong interactions. In fact, quantum chromodynamics isExpand
