Dispersion relations and the spin polarizabilities of the nucleon
(1998-02-26)
A forward dispersion calculation is implemented for the spin polarizabilities γ1, ⋯, γ4 of the proton and the neutron. These polarizabilities are related to the spin structure of the nucleon at low energies and are ...
Effect of bound nucleon internal structure change on nuclear structure functions
(Elsevier B.V., 2005-04-14)
Effect of bound nucleon internal structure change on nuclear structure functions is investigated based on local quark-hadron duality. The bound nucleon structure functions calculated for charged-lepton and (anti)neutrino ...
QCD spin physics: Partonic spin structure of the nucleon
(Elsevier Science, 2012-04)
We discuss some recent developments concerning the nucleon's helicity parton distribution functions: new preliminary data from jet production at RHIC suggest for the first time a non-vanishing polarization of gluons in the ...
Quark sea structure functions of the nucleon in a statistical model
(Springer, 2008-07-01)
Within a statistical model of linear confined quarks we obtain the flavor asymmetry and corresponding structure function of the nucleon. The model parameters are fixed by the experimental available data. The temperature ...
IMPROVED STATISTICAL QCD MODEL FOR THE QUARK CONTENT of THE NUCLEON
(World Scientific Publ Co Pte Ltd, 2010-08-01)
The neutron-to-proton ratio of the structure functions, F(2)(n)/F(2)(p), as well as the corresponding difference F(2)(p)-F(2)(n) are obtained within a statistical quark model for the nucleon, where the quark energy levels ...
The nucleon structure function and the quark effective potential
(Elsevier B.V., 2001-06-18)
By considering a statistical model for the quark content of the nucleon, where the quark levels are generated by a Dirac equation with a harmonic scalar-plus-vector potential, we note that a good fit for the ratio between ...
Strangeness content and structure function of the nucleon in a statistical quark model
(1999-12-01)
The strangeness content of the nucleon is determined from a statistical model using confined quark levels, and is shown to have a good agreement with the corresponding values extracted from experimental data. The quark ...
Nucleon-to-Roper electromagnetic transition form factors at large Q2
(2019-02-01)
High-precision nucleon-resonance electroproduction data on a large kinematic domain of energy and momentum transfer have proven crucial in revealing novel features of strong interactions within the Standard Model and ...
Spin-orbit induced backflow in neutron matter with auxiliary field diffusion Monte Carlo method
(American Physical SocCollege PkEUA, 2003)
Polarized structure functions of the nucleon in the resonance region
(2000-03-13)
We present predictions for the spin structure functions of the proton in the framework of a unitary isobar model for one-pion photo- and electroproduction. Our results are compared with recent experimental data from SLAC. ...
