Time-like pion electromagnetic form factors in kT factorization with the next-to-leading-order twist-3 contribution
We calculate the time-like pion electromagnetic form factor in the kT factorization formalism with the inclusion of the next-to-leading-order (NLO) corrections of the leading-twist and sub-leading-twist contributions. It's found that the total NLO correction can enhance (reduce) the magnitude (...
