The neutron charge form factor and target analyzing powers from 3He(e→,e′n) scattering

Abstract

The charge form factor of the neutron has been determined from asymmetries measured in quasi-elastic 3 − → He( e, e ′ n) at a momentum transfer of 0.67 (GeV/c) 2 . In addition, the target analyzing power, A o y , has been measured to study effects of final state interactions and meson exchange currents.

Nucleon electromagnetic form factors

“…Starting in the early 1990's, the neutron electric FF G En has been obtained in several experiments at MAMI, by measuring the beam-target asymmetry in the exclusive quasi-elastic scattering of electrons from polarized 3 He in the 3 He( e, e ′ n)pp reaction [Mey94,Bec99,Roh99,Ber03]. All the G En data from polarization experiments are shown in Fig.…”

Nucleon and flavor form factors in a light front quark model in AdS/QCD

“…In [21], the flavor form factors are extracted from the polarization data of the ratios of nucleon Sachs form factors. Diehl and Kroll [22] have recently extracted the flavor form factors from R p , R n , G The only parameter in the model is fixed by fitting to the data for the proton form factor ratio [45][46][47][48][49][50][51][52]54] and [38,55] ; (c)-(f) represent the contributions from different flavors. The experimental data are taken from [21,22].…”

Study of baryon octet charge form factors in perturbative chiral quark model

“…3, we present the Q 2 dependence of the charge form factor of the charged and neutral baryons respectively in the region Q 2 ≤ 1 GeV 2 , compared with the experimental data. [13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30] It is seen in the left panel of Fig. 3 that the theoretical charge form factor of proton is well fitted to the experimental data, and the charge form factors for the charged hyperons (Σ + , Σ − and Ξ − ) derived with the predetermined wave function behave the similar way since our calculations are restricted to the SU(3) chiral symmetry.…”
