Abstract
We present the first measurements of the ratios of cross sections and for the associated production of a boson with at least one charm or bottom quark jet. Jets have transverse momentum and pseudorapidity . These cross section ratios are measured differentially as a function of jet and boson transverse momenta, based on of collisions collected with the D0 detector at the Fermilab Tevatron Collider at . The measurements show significant deviations from perturbative QCD calculations and predictions from various event generators.
