The Meson Light - Cone Distribution Amplitudes
We give a complete re-analysis of the leading twist quark-antiquark light-cone distribution amplitudes of longitudinal and transverse mesons. We derive Wandzura-Wilczek type relations between diierent distributions and update the coeecients in their confor-mal expansion using QCD sum rules including next-to-leading order radiative corrections. We nd that the distribution amplitudes of quarks in...
متن کاملModels for Light-Cone Meson Distribution Amplitudes
Leading-twist distribution amplitudes (DAs) of light mesons like π, ρ etc. describe the leading nonperturbative hadronic contributions to exclusive QCD reactions at large energy transfer, for instance electromagnetic form factors. They also enter B decay amplitudes described in QCD factorisation, in particular nonleptonic two-body decays. Being nonperturbative quantities, DAs cannot be calculat...
متن کاملHigher twist light-cone distribution amplitudes of vector mesons in QCD
Amplitudes of hard (light-cone dominated) exclusive processes in QCD are expressed by the factorization formulae, which separate the short-distance dynamics from the longdistance one[1]. For those processes producing a (light) vector meson V (= ρ, ω,K, φ) in the final state, like exclusive semileptonic or radiative B decays (B → V eν, B → V + γ) and the hard electroproduction of vector mesons (...
متن کاملB Meson Light-cone Distribution Amplitudes and Heavy-quark Symmetry∗
Recently systematic methods based on the QCD factorization have been developed for the exclusive B meson decays into light mesons (for other approaches see). Essential ingredients in this approach are the light-cone distribution amplitudes for the participating mesons, which constitute nonperturbative long-distance contribution to the factorized amplitudes. For the light mesons (π, K, ρ, K, etc...
متن کاملModelling light-cone distribution amplitudes from non-relativistic bound states
We calculate light-cone distribution amplitudes for non-relativistic bound states, including radiative corrections from relativistic gluon exchange to first order in the strong coupling constant. We distinguish between bound states of quarks with equal (or similar) mass, m1 ∼ m2, and between bound states where the quark masses are hierarchical, m1 ≫ m2. For both cases we calculate the distribut...
