K+Λelectroproduction above the resonance region

Abstract: Background:In π + n and π − p electroproduction, conventional models cannot satisfactorily explain the data above the resonance region, in particular the transverse cross section. Although no high-energy L-T-separated cross-section data are available to date, a similar scenario can be inferred for K + Λ electroproduction. Purpose: Develop a phenomenological model for the p(γ * ,K + )Λ reaction at forward angles and high-energies. Propose a universal framework for interpreting charged-kaon and charged-pion elec… Show more

“…[28]. Here, we scaled all data to fixed values of −t=0.4 (GeV/c) 2 and x=0.3 using the separated Regge model by Vrancx and Ryckebusch (VR) [34] cross section predictions. The VR model extends the VGL Regge model by adding a hadronic model, which incorporates DIS light meson electroproduction at the amplitude level.…”

“…The proton exchange in the s-channel, though added to restore gauge invariance, plays a role in the transverse cross section dσ T /dt, which corresponds to photoproduction of π + at the photon point Q 2 = 0. It is reasonable to assume N * contributions in the resonance region [5,6]. The Q 2 dependence of the proton form factor, called the Dirac form factor, F 1 (Q 2 ) is determined from the Sachs electric and magnetic form factors G E (Q 2 ) and G M (Q 2 ) by using the relation…”

“…The unpolarized experimental cross sections, d 2 σ dtdφπ , listed in Table I have The results from the Regge amplitude based VR [15], CKY [12] and GPD-based GK [16,17] [2, 4] and CLAS (Hall B) data at high −t [10]. Both of these measurements were performed with a complete azimuthal (φ π ) coverage, which was integrated over in order to calculate the unpolarized cross sections.…”
