摘要：
In this paper, we calculate the rho-meson timelike electromagnetic form factors by employing the kT factorization approach. The theoretical ratio for the moduli of three helicity amplitudes and total cross-section for the annihilation/production process e(+)e(-)-> rho(+)rho(-) are analyzed at root s = 10.58GeV, where the BaBar experiment was done. The results for the moduli of the three helicity amplitudes F-i(Q(2))(i=LL,LT/TL,TL) are predicted between 60GeV(2) and 140GeV(2), and the three form factors G(i)(Q(2))(i=1,2,3) of rho meson are considered.
