Abstract

We present the effects of Fermi motion and different off-shell assumptions on the differential cross sections of photo- and electroproduction of the hypertriton. We found that Fermi motion plays an important role in these processes. Different off-shell assumptions yield different cross section magnitudes. The few available electroproduction data favor the assumption that the initial nucleon is off-shell and the final hyperon is on-shell. Measurement of the hypertriton photoproduction is urgently required to further support our findings.
