Experimental Status Report on Time-Like Baryon Form Factors

چکیده

Knowledge of the electromagnetic structure of hadrons is still far from complete. In this context the experimental study of the electromagnetic form factors (FF) of nucleons is of great importance. At small q2 we get information on charge distribution and magnetization current within the nucleon, while at high q2 form factors probe the valence quark distribution functions. Measurements of form factors are important to test the validity of QCD predictions, from the non-perturbative regime, near threshold, to the perturbative one at large q2. The timelike region is studied through the reactions pp → e+e− (1)

Two-Photon Annihilation into Baryon-Antibaryon Pairs

We study the handbag contribution to two-photon annihilation into baryon-antibaryon pairs at large energy and momentum transfer. We derive factorization of the process amplitude into a hard γγ → qq subprocess and form factors describing the soft qq → BB transition, assuming that the process is dominated by configurations where the (anti)quark approximately carries the full momentum of the (anti...

Future Perspectives on Baryon Form Factor Measurements with BES III

The electromagnetic structure of hadrons, parameterised in terms of electromagnetic form factors, EMFF’s, provide a key to the strong interaction. Nucleon EMFF’s have been studied rigorously for more than 60 years but the new techniques and larger data samples available at modern facilities have given rise to a renewed interest for the field. Recently, the access to hyperon structure by hyperon...

Baryon form factors : Model – independent results ∗

Baryon form factors can be analyzed in a largely model–independent fashion in terms of two complementary approaches. These are chiral perturbation theory and dispersion relations. I review the status of dispersive calculations of the nucleon electromagnetic form factors in the light of new data. Then, I present the leading one–loop chiral perturbation theory analysis of the hyperon and the stra...

Baryon masses in a chiral expansion with meson-baryon form factors

The chiral expansion of the one-loop corrections to baryon masses is examined in a generic meson-cloud model with meson-baryon form factors. For pion loops, the expansion is rapidly convergent and at fourth order inmπ accurately reproduces the full integral. In contrast, the expansion is found to converge very slowly for kaon loops, raising questions about the usefulness of chiral expansions fo...

Baryon form factors in chiral perturbation theory

We analyze the electromagnetic form factors of the ground state baryon octet to fourth order in relativistic baryon chiral perturbation theory. Predictions for the Σ charge radius and the Λ–Σ0 transition moment are found to be in excellent agreement with the available experimental information. Furthermore, the convergence behavior of the hyperon charge radii is shown to be more than satisfactory.
