Title: Separated kaon electroproduction cross section and the kaon form factor from 6 GeV JLab data

Abstract

The ¹H(e,e ^'K ⁺)Λ reaction was studied as a function of the Mandelstam variable -t using data from the E01-004 (FPI-2) and E93-018 experiments that were carried out in Hall C at the 6 GeV Jefferson Laboratory. The cross section was fully separated into longitudinal and transverse components, and two interference terms at four-momentum transfers Q ² of 1.00, 1.36, and 2.07 GeV ². The kaon form factor was extracted from the longitudinal cross section using the Regge model by Vanderhaeghen et al. [Phys. Rev. C 57, 1454 (1998)]. Here, the results establish the method, previously used successfully for pion analyses, for extracting the kaon form factor. Data from 12 GeV Jefferson Laboratory experiments are expected to have sufficient precision to distinguish between theoretical predictions, for example, recent perturbative QCD calculations with modern parton distribution amplitudes. The leading-twist behavior for light mesons is predicted to set in for values of Q ² between 5 and 10 GeV ², which makes data in the few-GeV regime particularly interesting. Finally, the Q ² dependence at fixed x and -t of the longitudinal cross section that we extracted seems consistent with the QCD factorization prediction within the experimental uncertainty.

Exploring Hadron Structure Through Exclusive Kaon Electroproduction

Thesis/Dissertation Carmignotto, Marco A.

The kaon electroproduction cross section was extracted from data from the E93-018 and the E01-004 (FPI-2) experiments taken at the Thomas Jefferson National Accelerator Facility in the p(e,e'K ⁺)Λ channel. The cross section was fully separated into longitudinal, transverse, and two interference components at four-momentum transfers Q ² of 1.0 (GeV/c) ² (with center of mass energy W=1.81 GeV), 1.36 and 2.07 (GeV/c) ² (W=2.31 GeV). The kaon form factor (FK) was extracted from the longitudinal cross section in these kinematics using the Regge model by Vanderhaeghen, Guidal, and Laget.

Deep Exclusive Pseudoscalar Meson Production at Jefferson Lab Hall C

Thesis/Dissertation Basnet, Samip

Measurements of exclusive meson production are a useful tool in the study of hadronic structure. In particular, one can discern the relevant degrees of freedom at different distance scales through these studies. In the transition region between low momentum transfer (where a description of hadronic degrees of freedom in terms of effective hadronic Lagrangians is valid) and high momentum transfer (where the degrees of freedom are quarks and gluons), the predictive power of Quantum Chromodynamics (QCD), the theory of the strong interaction, is limited due to the absence of a complete solution. Thus, one has to rely upon experimental datamore »« less

The Pion Charge Form Factor Through Pion Electroproduction

Thesis/Dissertation Horn, Tanja

The goal of Jefferson Lab experiment E01-004 (Fπ-2) was the measurement of the longitudinal and transverse cross sections via pion electroproduction from hydrogen and deuterium for the purpose of extracting the charged pion form factor using pole dominance. The data were taken at two values of Q ² (1.60 and 2.45 GeV/c) ². In order to attain full coverage in Φ _π, charged pions were detected in parallel kinematics (along the direction of momentum transfer, q), and at ±3 degrees off the direction of momentum transfer. For each Q ² data were taken for two values of the virtual photonmore »« less
