Baryon Form Factors at High Momentum Transfer and Generalized Parton Distributions
نویسنده
چکیده
Nucleon form factors at high momentum transfer t are treated in the framework of generalized parton distributions (GPD’s). The possibility of obtaining information about parton high transverse momentum components by application of GPD’s to form factors is discussed. This is illustrated by applying an ad-hoc 2-body parton wave function to elastic nucleon form factors F1 and F2, the N → ∆ transition magnetic form factor G∗ M , and wide angle Compton scattering (WACS) form factor R1.

Baryon Form Factors at High Momentum Transfer and Gpd’s
Nucleon elastic and transition form factors at high momentum transfer −t are treated in terms of generalized parton distributions in a two-body framework. In this framework the high −t dependence of the form factors give information about the high k⊥ , or short distance b⊥ correlations of nucleon model wave functions. Applications are made to elastic and resonance nucleon form factors, and real...
متن کاملChiral structure of nucleon gravitational form factors
We study the low momentum behavior of nucleon gravitational form factors in the framework of the heavy baryon chiral perturbation theory. At zero recoil they determine the momentum and spin apportion between nucleon constituents. Our result provides an insight into the response of the nucleon's pion cloud to an external weak gravitational field and establishes a theoretical framework for extrap...
متن کاملTwo-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...
متن کاملStudy of Generalized Parton Distributions with Clas at Jefferson Lab
In the past nearly five decades of electron scattering, experiments have focussed either on the measurements of form factors using exclusive processes or on measurements of inclusive processes to extract deep inelastic structure functions. Elastic processes measure the momentum transfer dependence of form factors, while the latter ones probe the quark’s longitudinal momentum and helicity distri...
متن کاملProbing quark-distribution amplitudes through generalized parton distributions at large momentum transfer.
In the large momentum transfer limit, generalized parton distributions can be calculated through a QCD factorization theorem which involves perturbatively calculable hard kernels and light-cone parton distribution amplitudes of hadrons. We illustrate this through the H(q)(x,xi,t) distribution for the pion and the proton, presenting the hard kernels at leading order. As a result, experimental da...
