Meson Cloud Contribution to Nucleon Structure in Semi-Relativistic Constituent Quark Model
Abstract
The quark pair creation operator added to a convensional confined-quark Hamiltonian generates an extended Fock space wavefunction for a nucleon including meson cloud. In the harmonic oscillator basis, we consider the 1/2^+ baryons as mixed states of the three low lying SU multiplets truncated at the sd ( n=0,2 ) shell. Including the effect of antisymmetrization, we study the meson cloud contribution to one-body and two-body observables calculated for the ground states of nucleons. The form factor and magnetic moment as well as charge, mass, and magnetic radii will be investigated as they should provide good size constraints.
