چکیده
We investigate the strange and flavor-singlet electric and magnetic form factors of the nucleon within the framework of the SU(3) chiral quark-soliton model. Isospin symmetry is assumed and the symmetry-conserving SU(3) quantization is employed, rotational and strange-quark mass corrections being included. For the experiments G0, A4, and HAPPEX II we predict the quantitiesG0E+βG 0 M andG s E+βG s M . The dependence of the results on the parameters of the model and the treatment of the Yukawa asymptotic behavior of the soliton are investigated.

We summarize the results of the chiral quark-soliton model (χQSM) concerning basically all form factors necessary to interpret the present data of the parity violating electron scattering experiments SAMPLE, HAPPEX, A4 and G0. The results particularly focus on the recently measured asymmetries and the detailed data for various combinations of GsM , G s E , G̃ p A and G̃ n A at Q 2 = 0.1 GeV. The ...
متن کاملFlavor content of nucleon form factors in a VMD approach
The strange form factors of the nucleon are studied in a two-component model consisting of a three-quark intrinsic structure surrounded by a meson cloud. A comparison with the available experimental world data from the SAMPLE, PVA4, HAPPEX and G0 collaborations shows a good overall agreement. It is shown that the strangeness contribution to the electric and magnetic form factors is of the order...
متن کاملToday ’ s View on Strangeness
There are several different experimental indications, such as the pion-nucleon Σ term and polarized deep-inelastic scattering, which suggest that the nucleon wave function contains a hidden ss̄ component. This is expected in chiral soliton models, which also predicted the existence of new exotic baryons that may recently have been observed. Another hint of hidden strangeness in the nucleon is pr...

The strange form factors of the nucleon are studied in a two-component model consisting of a three-quark intrinsic structure surrounded by a meson cloud. A comparison with the available experimental world data from the SAMPLE, PVA4, HAPPEX and G0 collaborations shows a good overall agreement. The strange magnetic moment is found to be positive μs = 0.315 μN . PACS numbers: 13.40.Gp, 12.40.Vv, 1...
متن کاملStrange matrix elements of the nucleon
Prediction, measurement and understanding of strangeness in the nucleon have proven to be significant challenges for both theory and experiment. Of particular interest at present are the strangeness electric and magnetic form factors. Experimental results have been reported by SAMPLE[1] and HAPPEX[2], and other groups are also planning experiments.[3] A number of lattice QCD studies have been r...
