We investigate the transverse polarization of a hyperon produced in thehigh-energy unpolarized proton-proton collision, $pp\to\Lambda^\uparrow X$,based on the collinear twist-3 factorization formalism. We focus on thecontribution from the twist-3 distribution in one of the unpolarized proton andthe transversity fragmentation function for the final hyperon. Utilizing the"master formula" for the soft-gluon-pole cross section, we clarify the reasonfor why it receives only the derivative term of the twist-3 distribution. Wealso present the first computation of the soft-fermion-pole cross section andfound that it vanishes. This means that the derivative of the soft-gluon-polefunction is the only source for the twist-3 cross section from the unpolarizedtwist-3 distribution, which provides a useful basis for a phenomenologicalanalysis.
