We have calculated the unpolarized dihadron fragmentation functions (uDiFFs) of pions and kaons using the nonlocal chiral-quark model (NLChQM) and evolved our results to the transferred momentum scale Q2=4GeV2 by the QCD evolution equations. These uDiFFs have also been computed in the Nambu–Jona-Lasinio-jet (NJL-jet) model for the sake of comparison. We find that there is substantial difference between the results of these two models. Furthermore, the DiFFs of u→π+π and g→π+π at Q2=109GeV2 in these two models are presented in comparison with the parametrizations fitted by the Monte Carlo event generator JETSET.
