STRANGENESS PRODUCTION USING ELECTRONS
The 1H(e,e′K+)Λ reaction was studied as a function of squared four-momentum transfer, Q2, between 0.52 and 2.00 (GeV/c)2, and of the virtual photon polarization parameter, ∊, at Jefferson Lab. From this data, the first accurate separation of the longitudinal and transverse cross sections in this reaction was achieved. The results are discussed and compared to representative model calculations.
