چکیده

The existence of a shallow or virtual tetraquark state, c c ū d̄, is discussed. Using the putative masses for the doubly charmed baryons (c c u/c c d) from SELEX, the mass of the c c ū d̄ state is estimated to be about 3.9GeV , only slightly above the DD threshold. The experimental signatures for various c c ū d̄ masses are also discussed. Typeset using REVTEX 1

Flavor Asymmetry of the Polarized Light Sea: Models vs. Data

The flavor asymmetry of the polarized light sea, ∆ū −∆d̄, discriminates between different model calculations of helicity densities. We show that the chiral chromodielectric model, differently from models based on a 1/Nc expansion, predicts a small value for this asymmetry, what seems in agreement with preliminary HERMES data. 1. Following the discovery that the quark contribution to the spin of ...

The d̄ − ū asymmetry of the proton in a Pion Cloud Model approach

We study the d̄− ū asymmetry of the proton in a model approach in which hadronic fluctuations of the nucleon are generated through gluon splitting and recombination mechanisms. Within this framework, it is shown that the d̄ − ū asymmetry of the proton is consistently described by including only nucleon fluctuations to |πN〉 and |π∆〉 bound states. Predictions of the model closely agree with the rec...

Omega Meson Cloud and the Proton’s Light Anti-Quark Distributions

We use the meson cloud model of the nucleon to calculate distribution functions for (d̄− ū) and d̄/ū in the proton. Including the effect of the omega meson cloud, with a coupling constant g ω/4π ≈ 8, allows a reasonably good description of the data. There has been considerable interest in the flavor dependence of the proton’s quark distributions. About ten years ago, the NMC measurement of the in...
