Abstract

We study exclusive electroproduction of two hadrons where one or both of the hadrons is a higherspin resonance whose decay is analysed. Interesting electroproduction experiments of this type are discussed. A complete formal apparatus is given for the decay analysis of spin‐J particles produced in this way with polarized or unpolarized electron beams and targets. The cases J = 1, 3/2, 2 and 5/2 are worked out in detail. A conventional helicity frame analysis in terms of s‐channel helicity amplitudes is given. Also we rearrange the formalism for use in the Gottfried‐Jackson frame with everything given in terms of t‐channel helicity amplitudes. The t‐channel formalism makes it possible to completely separate the contributions from longitudinal and transverse virtual photon t‐channel helicity states when only the laboratory azimuthal angle between the lepton and hadron planes is variable.
