英文摘要	We study the e(+) e(-) -> VP and e(+) e(-) -> TP processes in the perturbative QCD approach based on k(r) factorization, where the P, V and T denotes a light pseudoscalar, vector, and tensor meson, respectively. We point out in the case of e(+) e(-) -> TP transition due to charge conjugation invariance, only three channels are allowed: e(+) e(-) -> a(2)(+/-)pi(-/+), e(+) e(-) -> K-2K-+/-(-/+) and the V-spin suppressed e(+) e(-) -> K-2(0)(K) over bar (0) + K-2*(0)(K) over bar (0). Cross sections of e(+) e(-) -> VP and e(+) e(-) -> TP at root s = 3.67 GeV and root s = 10.58 GeV are calculated and the invariant mass dependence is found to favor the 1/s(4) power law. Most of our theoretical results are consistent with the available experimental data and other predictions can be tested at the ongoing BESIII and forthcoming Belle-II experiments.
