No significant signal is found in the invariant mass range from 6.7 to 7.2 GeV/c(2). Upper limits are set at 95% credibility level on the ratio of the Xi bc0 production cross-section times its branching fraction to D(0)pK(-) relative to that of the Lambda b0 -> D0pK- decay. The limits are set as a function of the Xi bc0 mass and lifetime hypotheses, in the rapidity range from 2.0 to 4.5 and in the transverse momentum region from 5 to 25 GeV/c. Upper limits range from 1.7 x 10(-2) to 3.0 x 10(-1) for the considered Xi bc0 mass and lifetime hypotheses. %K B physics %K Hadron-Hadron scattering (experiments) %K Heavy quark production %K QCD %K Spectroscopy %R 10.1007/JHEP11(2020)095 %U https://arxiv.org/abs/2009.02481 %U https://doi.org/10.1007/JHEP11(2020)095 %P 095-21pp
