Double charmonium production at B factories within light cone formalism
This report is devoted to the study of the processes e + e − → J/Ψη c , J/Ψη c , ψ η c , ψ η c within light cone formalism. It is shown that the results of the calculation of the cross sections of these processes are in agreement with Belle and BaBar experiments. It is also shown that relativistic and radiative corrections to the cross sections play crucial role in the achievement of the agreem...
متن کاملOn 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 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 کاملConnecting generalized parton distributions and light-cone wave functions
The relation of generalized (skewed) quark distributions to nucleon wave functions is discussed in the context of light-cone quantization.
متن کاملLight-cone wave functions of mesons
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, C...
