Quark recombination model for polarizations in inclusive hyperon productions at high energy
We investigate the transverse polarization of hyperons produced by the photon induced reactions using the quark recombination model. This model reproduces polarizations of hadrons produced by the hadron-hadron collisions and accounts for the origin of the empirical rule by DeGrand and Miettinen. We find significant polarizations in the hyperon photoproduction by applying this model to the $γN \ra \Lam $ $(Σ^{0}) + X$ reaction.
