Recursive Fragmentation Model with Quark Spin. Application to Quark Polarimetry
An elementary recursive model accounting for the quark spin in the fragmentation of a quark into mesons is presented. The quark spin degree of freedom is represented by a two-components spinor. Spin one meson can be included. The model produces Collins effect and jet handedness. The influence of the initial quark polarisation decays exponentially with the rank of the meson, at different rates f...
متن کاملQuark - Resonance Model
We construct an effective Lagrangian for low energy hadronic interactions through an infinite expansion in inverse powers of the low energy cutoff Λχ of all possible chiral invariant non-renormalizable interactions between quarks and mesons degrees of freedom. We restrict our analysis to the leading terms in the 1/Nc expansion. The effective expansion is in (μ /Λχ) P ln(Λχ/μ 2)Q. Concerning the...
متن کاملThe Spin–Symmetry of the Quark Model
Corrections to the exact heavy–quark symmetry results are expected to follow the 1/mQ mass effect of the heavy–quark. We show, by an explicit calculation, that there is something other than the mass effect that suppresses the breaking of the spin symmetry.
متن کاملProton spin structure and quark-parton model
The alternative to the standard formulation of the quark-parton model is proposed. Our approach is based on the solution of the master equations relating the structure and distribution functions, which consistently takes into account the intrinsic quark motion in contradistinction to the standard infinite momentum approach, in which this motion is latently suppressed. The model well reproduces ...
متن کاملIs Nucleon Spin Structure Inconsistent with Constituent Quark Model?
Hadron structure studies might be traced back to Fermi-Yang [1] and Sakata models [2]. Gell-Mann [3] and Zweig [4] proposed the quark model of hadrons. Lepton-nucleon deep inelastic scattering (DIS) [5] verified the quark structure of hadrons. However the quark revealed in DIS is found to be different from the quark as a carrier of SU(3) symmetry in Gell-Mann-Zweig model. The former is almost a...
