英文摘要	Inspired by the recent measurements of the lic meson production at LHC experiments, we investigate the relativistic correction effect for the fragmentation functions of gluon/charm quark fragmenting into Tic, which constitute the crucial nonperturbative element for the Tic production at high p(T). Employing three distinct methods, we calculate the next-to-leading-order (NLO) relativistic correction to g -> eta(c) fragmentation function in the NRQCD factorization framework, as well as verifying the existing NLO result for the c -> eta(c) fragmentation function. We also study the evolution behavior of these fragmentation functions with the aid of the DGLAP equation.
