The 1 H(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 Lab. 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, Guidal, and Laget. The results establish the method, previously used successfully for pion analyses, for extracting the kaon form factor. Data from 12 GeV Jefferson Lab experiments are expected to have sufficient precision to distinguish between theoretical predictions, for example recent perturbative QCD calculations with modern parton distribution amplitudes. The leadingtwist behavior for light mesons is predicted to set in for values of Q 2 between 5-10 GeV 2 , which makes data in the few GeV regime particularly interesting. The Q 2 dependence at fixed x and −t of the longitudinal cross section we extracted seems consistent with the QCD factorization prediction within the experimental uncertainty.The description of hadrons in terms of their constituents, the quarks and gluons, is a fundamental challenge in nuclear physics. Properties such as total charge and magnetic moments are well described in a constituent quark framework. However, charge and current distributions, which are more sensitive to the underlying dynamic processes in hadrons, are still not well described. The 1 H(e, e ′ K + )Λ reaction provides the simplest system including strangeness, and is thus an effective experimental test of flavor degrees of freedom.The electromagnetic form factors of hadrons are di-rectly connected to their internal structure. Measurements of the onset of the asymptotic, pointlike regime are an essential experimental verification of a key prediction of Quantum Chromodynamics (QCD) [1]. The form factors of light, two-quark hadronic systems like pions and kaons are of special importance as their asymptotic behavior is expected to set in earlier than that of threequark systems. The relevance of pion and kaon form factors, for both experiment and theory, is evident in the literature [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18].
