No significant signal is observed within the invariant mass range of 3.6 to 4.0GeV/c(2). Upper limits are set on the ratio R of the production cross-section times the total branching fraction of the Omega(+)(cc) -> Xi K-+(c)-pi(+) decay with respect to the Xi(++)(cc) -> Lambda K-+(c)-pi(+)pi(+) decay. Upper limits at 95% credibility level for R in the range 0.005 to 0.11 are obtained for different hypotheses on the Omega(+)(cc) mass and lifetime in the rapidity range from 2.0 to 4.5 and transverse momentum range from 4 to 15 GeV/c. %K charmed baryons %K limits on production of particles %K charmed quarks %K experimental tests %R 10.1007/s11433-021-1742-7 %U https://arxiv.org/abs/2105.06841 %U https://doi.org/10.1007/s11433-021-1742-7 %P 101062-12pp
