Light-cone wave functions of mesons
نویسنده
چکیده
A review of light-cone, covariant and gauge-invariant wave-functions of mesons is presented. They are basic non-perturbative objects needed for hard exclusive processes and for the method of light-cone QCD sum rules. The emphasis is on the vector mesons and a new (model-independent) way of computing the mass corrections of vector-meson wave functions is given. Key-Words: Non-pertrubative QCD, Conformal expansion.

On Transverse-Momentum Dependent Light-Cone Wave Functions of Light Mesons
Transverse-momentum dependent (TMD) light-cone wave functions of a light meson are important ingredients in the TMD QCD factorization of exclusive processes. This factorization allows one conveniently resum Sudakov logarithms appearing in collinear factorization. The TMD light-cone wave functions are not simply related to the standard light-cone wave functions in collinear factorization by inte...
متن کاملRenormalization of Chiral-Even Twist-3 Light-cone Wave Functions for Vector Mesons in QCD
We present the one-loop anomalous dimension matrices for the chiral-even twist-3 (nonsinglet) conformal operators, which govern the scale-dependence of the vector meson light-cone wave functions through the conformal expansion. It is clarified that the constraints from the charge-conjugation invariance and the chirality conservation allow only one independent anomalous dimension matrix for each...
متن کاملMeasurement of Light-Cone Wave Functions by Diffractive Dissociation
Diffractive dissociation of particles can be used to study their light-cone wave function. Results from Fermilab experiment E791 for diffractive dissociation of 500 GeV/c π− mesons into di-jets are presented. The results show that the |qq̄〉 light-cone asymptotic wave function describes the data well for Q2 ∼ 10 (GeV/c)2 or more. Evidence for color transparency comes from a measurement of the A-d...
متن کاملTHE SPINLESS SALPETER EQUATION AND MESON DYNAMICS
Applying the variational method, the spinless reduced Bethe-Salpeter (RBS) equation is solved for the mesonic systems, and the mass spectra are obtained. The method is applied to the Hamiltonian with the Gaussian and hydrogen-type trial wave functions, and different potential models are examined. The results for the different potentials are in challenge in light mesons, while they are consisten...
متن کاملHard constituent quarks and electroweak properties of pseudoscalar mesons
The high momentum components generated in the wave function of pseudoscalar mesons by the one-gluon-exchange interaction are investigated within a relativistic constituent quark model. Adopting the light-cone formalism, the sensitivity of the weak decay constant and the charge form factor to hard constituent quarks is illustrated. Phys. Lett. B, in press. The investigation of the electroweak pr...
