Electromagnetic Form Factors of Baryons
نویسنده
چکیده
Electromagnetic form factors of the nucleon and its excitations (baryon resonances) provide a powerful tool to investigate the structure of the nucleon. These form factors can be measured in electroproduction as a function of the four-momentum squared q = −Q of the virtual photon. In this contribution we present a simultaneous study of the elastic form factors of the nucleon and the transition form factors, for both of which there exists exciting new data. The analysis is carried out in the framework of a collective model of the nucleon. We address the effects of relativistic corrections and couplings to the meson cloud.

Electromagnetic form factors of the SU(3) octet baryons in the semibosonized SU(3) Nambu-Jona-Lasinio model.
The electromagnetic form factors of the SU(3) octet baryons are investigated in the semibosonized SU(3) Nambu–Jona-Lasinio model (chiral quark-soliton model). The rotational 1/N c and strange quark mass corrections in linear order are taken into account. The electromagnetic charge radii of the nucleon and magnetic moments are also evaluated. It turns out that the model is in * 1 a remarkable go...
متن کاملMagnetic Dipole, Electric Quadrupole and Magnetic Octupole Moments of the ∆ Baryons in Light Cone QCD Sum Rules
Due to the very short life time of the ∆ baryons, a direct measurement on the electromagnetic moments of these systems is almost impossible in the experiment and can only be done indirectly. Although only for the magnetic dipole moment of ∆++ system there is some experimental data, the theoretical, phenomenological and lattice calculations could play crucial role. In present work, by calculatin...
متن کاملAlgebraic models of hadron structure: I. Nonstrange baryons
We introduce an algebraic framework for the description of baryons. Within this framework we study a collective string-like model and show that this model gives a good overall description of the presently available data. We discuss in particular masses and electromagnetic couplings, including the transition form factors that can be measured at new electron facilities.
متن کاملBaryons on the lattice
I comment on progress of lattice QCD techniques and calculations. Recent results on pentaquark masses as well as of the spectrum of excited baryons are summarizned and interpreted. The present state of calculations of quantities related to the nucleon structure and of electromagnetic transition form factors is surveyed.
متن کاملElectromagnetic form factors in a collective model of the nucleon.
We study the electromagnetic form factors of the nucleon in a collective model of baryons. Using the algebraic approach to hadron structure, we derive closed expressions for both elastic and transition form factors, and consequently for the helicity amplitudes that can be measured in electroand photoproduction. Effects of spin-flavor symmetry breaking and of swelling of hadrons with increasing ...
