Next-to-leading-order time-like rho electromagnetic form factors in $k_{\mathrm{T}}$ factorization

Ya-Lan Zhang, Si-Yu Wang, Chao Wang +2

We calculate the time-like $\ddot{I}$ electromagnetic (EM) form factor in the $k_T$ factorization formalism by including the next-to-leading-order (NLO) corrections of the leading-twist…
