Title: Study of leading twist light cone wave functions of the J/{psi} meson

Abstract

This paper is devoted to the study of leading twist light cone wave functions of the J/{psi} meson. The moments of these wave functions have been calculated within three approaches: potential models, nonrelativistic QCD, and QCD sum rules. Using the results obtained within these approaches the models for the light cone wave functions of leading twist have been proposed. Similarly to the wave function of the {eta}{sub c} meson, the leading twist light cone wave functions of the J/{psi} meson have very interesting properties at scales {mu}>m{sub c}: improvement of the accuracy of the model, appearance of a relativistic tail, and violation of nonrelativistic QCD velocity scaling rules. The last two properties are the properties of true leading twist light cone wave functions of the J/{psi} meson.

  • In this paper leading twist light cone wave functions of 2S state charmonium mesons are studied and models of these functions are built.
  • Predictions for e{sup +}e{sup -}{yields}J/{psi}{eta}{sub c} from previous studies are made by taking charmonia as a nonrelativistic bound state and by using nonrelativistic QCD (NRQCD) approach. The predicted cross section is smaller by an order of magnitude than the experimentally observed cross section. We study the process by taking charm quark as a light quark and use light-cone wave functions to parameterize nonperturbative effects related to charmonia. The total cross section of e{sup +}e{sup -}{yields}J/{psi}{eta}{sub c} can be predicted, if these wave functions are known. Motivated by studies of light-cone wave functions of light hadrons, we make a reasonable assumptionmore » of the forms of light-cone wave functions. With these light-cone wave functions we can obtain the cross section which is closer to the experimentally observed than that from the NRQCD approach. We also discuss in detail the difference between two approaches.« less
  • We give a complete reanalysis of the leading twist quark-antiquark light-cone distribution amplitudes of longitudinal and transverse {rho} mesons. We derive Wandzura-Wilczek-type relations between different distributions and update the coefficients in their conformal expansion using QCD sum rules, including next-to-leading order radiative corrections. We find that the distribution amplitudes of quarks inside longitudinally and transversely polarized {rho} mesons have a similar shape, which is in contradiction to previous analyses. {copyright} {ital 1996 The American Physical Society.}
  • We explore the possibility to construct higher-twist parton distributions in a nucleon at some low reference scale from convolution integrals of the light-cone wave functions (WFs). To this end we introduce simple models for the four-particle nucleon WFs involving three valence quarks and a gluon with total orbital momentum zero, and estimate their normalization (WF at the origin) using QCD sum rules. We demonstrate that these WFs provide one with a reasonable description of both polarized and unpolarized parton densities at large values of the Bjorken variable x{>=}0.5. Twist-three parton distributions are then constructed as convolution integrals of qqqg andmore » the usual three-quark WFs. The cases of the polarized structure function g{sub 2}(x,Q{sup 2}) and single transverse spin asymmetries are considered in detail. We find that the so-called gluon pole contribution to twist-three distributions relevant for single spin asymmetry vanishes in this model, but is generated perturbatively at higher scales by the evolution, in the spirit of Glueck-Reya-Vogt parton distributions.« less
  • The decays of pseudoscalar bottomonium {eta}{sub b} into a pair of vector charmonia, J/{psi}J/{psi}, J/{psi}{psi}{sup '}, {psi}{sup '{psi}'}, are considered in the light cone formalism. Relativistic and leading logarithmic radiative corrections to the amplitudes of these processes are resummed. It is shown that the small value for the branching ratio of the decay {eta}{sub b{yields}}J/{psi}J/{psi} obtained within the leading-order nonrelativistic QCD is a consequence of a fine-tuning between certain parameters, which is broken when relativistic and leading logarithmic radiative corrections are taken into account. As a result, the branching ratio obtained in this paper is enhanced by an order ofmore » magnitude.« less
