Diffractive ρ-meson Leptoproduction on Polarized Nucleon
نویسنده
چکیده
The amplitude of diffractive ρ (and open quark) leptoproduction on a polarized target is calculated in the leading log approximation of pQCD using the hadron-parton duality hypothesis. The spin-spin asymmetry is expressed in terms of the spin dependent gluon and quark structure functions in the small x region. Therefore the γ∗+p → ρ+ p reaction provides a promising tool to study the spin dependent gluon distribution ∆G(x, q2). E-mail: [email protected]

Diffractive leptoproduction of vector mesons in QCD.
We demonstrate that the distinctive features of the forward differential cross section of diffractive leptoproduction of a vector meson can be legitimately calculated in perturbative QCD in terms of the light-cone qq̄ wave function of the vector meson and the gluon distribution of the target. In particular, we calculate the Q2 and nuclear dependence of the diffractive leptoproduction of vector m...
متن کاملA model prediction for polarized antiquark flavor asymmetry
Polarized flavor asymmetry ∆¯ u/∆ ¯ d is investigated in a meson-cloud model. A polarized nucleon splits into a ρ meson and a baryon, then the polarized ρ meson interacts with the virtual photon. Because of the difference between the longitudinally polarized distributions ∆¯ u and ∆ ¯ d in ρ, the polarized flavor asymmetry is produced in the nucleon. In addition, we show that the g 2 part of ρ ...
متن کاملSudakov Form Factors in Leptoproduction of Vector Mesons
It is shown that Sudakov form factors for a colour dipole in a QCDinspired model of leptoproduction of vector mesons reduce the value of the cross section of the process by an order of magnitude. They suppress the large size quark-antiquark pairs and unequal sharing of energy among the components of the dipole. Some freedom in the choice of the model parameters is also discussed. The idea of in...
متن کاملMeson Cloud of the Nucleon in Polarized Semi - Inclusive Deep - Inelastic Scattering
We investigate the possibility of identifying an explicit pionic component of the nucleon through measurements of polarized ∆ ++ baryon fragments produced in deep-inelastic leptoproduction off polarized protons, which may help to identify the physical mechanism responsible for the breaking of the Got-tfried sum rule. The pion-exchange model predicts highly correlated polariza-tions of the ∆ ++ ...
متن کاملAnomalous A - dependence of diffractive leptoproduction of radial excitation ρ ′ ( 2 S )
A b s t r a c t We predict a strikingly different A and Q 2 dependence of quasielastic leptoproduction of the ρ 0 (1S)-meson and its radial excitation ρ ′ (2S) on nuclei. Whereas for the ρ 0 production nuclear transparency T A decreases monotonically with A, for the ρ ′ nuclear transparency T A can have the counterintuitive nonmonotonic A-dependence, having the minimum for light nuclei, and inc...
