[en] Production of large-psub(t) scalar (O⁺⁺) and pseudoscalar (O^+-) glueballs in hadronic collisions is investigated. The contribution of subprocesses q anti q → Gg, gq→Gq, gg→Gg i s taken into account. The analysis is provided by using the helicity formalism. Helicity amplitudes and differential cross sections of glueball production for various beams and targets are obtained. It is shown that mechanisms considered lead to linear polarization of the final gluon jet, even if initial particles are unpolarized. For this case a density matrix of the final gluon is obtained. This sign of the polarization depends on th parity of the glueball and opposite for subprocesses q anti q →Gg and gg→Gg
