|Abstract: ||We calculate threshold soft-gluon corrections to total cross sections and transverse momentum
distributions for bottom and charm quark production in fixed-target experiments,
considering both pp and −p interactions. We investigate the quality of the near threshold
soft-gluon approximation at next-to-leading order (NLO) and calculate next-to-nextto-
leading order (NNLO) corrections through next-to-next-to-next-to-leading-logarithmic
(NNNLL) accuracy, including some virtual terms. We find that the NNLO threshold
corrections reduce the factorization and renormalization scale dependence of the cross
