We present the analysis of data samples taken by the WA77 experiment for pi-Be interactions at 300 and 150 GeV/c. The trigger selects a pair of oppositely charged particles with p(T) greater-than-or-equal-to 2 GeV/c balancing the transverse momentum of a third high-p(T) track. The primary aim of this experiment was the search for higher-twist production, mainly that of vector mesons. Since there are definite predictions for the polarization of mesons produced in fragmentation and through the higher-twist mechanism, we study the polarization properties of clearly identified mesons, namely the phi and f2(1270) mesons. The results are compatible with no polarization. This can be interpreted as a production dominantly due to parton fragmentation
