- We test the validity of the Goldstone boson equivalence theorem by calculating the cross sections for the real hadronic processes ppXLXL+anything(XL=WLorZL) in hadron colliders. For the subprocesses, we use the exact amplitudes, and also the amplitudes given by the equivalence theorem. For the low MXLXL region (200-400 GeV), there are substantial discrepancies between the two cross sections. In addition to MW2s^ terms, there are significant contributions from the MH2s^ terms present in the difference between the exact and equivalence amplitude for the subprocesses. In particular, MH2s^ terms are very important for MHs. 1994 The American Physical Society.
