# One-loop amplitudes for four-point functions with two external massive quarks and two external massless partons up to O({epsilon}{sup 2})

@article{JGKorner2006OneloopAF, title={One-loop amplitudes for four-point functions with two external massive quarks and two external massless partons up to O(\{epsilon\}\{sup 2\})}, author={J.G.Korner and Z. Merebashvili and M. Rogal}, journal={Physical Review D}, year={2006}, volume={73}, pages={034030} }

We present complete analytical O({epsilon}{sup 2}) results on the one-loop amplitudes relevant for the next-to-next-to-leading order (NNLO) quark-parton model description of the hadroproduction of heavy quarks as given by the so-called loop-by-loop contributions. All results of the perturbative calculation are given in the dimensional regularization scheme. These one-loop amplitudes can also be used as input in the determination of the corresponding NNLO cross sections for heavy flavor… Expand
