Photoproduction of the Hypertriton

Abstract

In the framework of the impulse approximation we study the photoproduction of the hypertriton ${}_{\Lambda }^3$H by using realistic ${}^3$He wave functions obtained as solutions of Faddeev equations with the Reid soft-core potential for different ${}_{\Lambda }^3$H wave functions. We obtain relatively small cross sections of the order of 1 nb. We also find that the influence of Fermi motion is important, while the effect of different off-shell assumptions on the cross section is not too significant.
