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-2*k-+/-(-/+) 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.
