A search for the doubly charmed baryon $$\Xi_{cc}^+$$ is performed through its decay to the $$Λ$$ $$^{+}_{c}$$ K–π+ final state, using proton-proton collision data collected with the LHCb detector at centre-of-mass energies of 7, 8 and 13 TeV. The data correspond to a total integrated luminosity of 9 fb–1. No significant signal is observed in the mass range from 3.4 to 3.8 GeV/c2. Upper limits are set at 95% credibility level on the ratio of the $$\Xi_{cc}^+$$ production cross-section times the branching fraction to that of $$Λ$$ $$^{+}_{c}$$ and $$\Xi_{cc}^{++}$$ baryons. The limits are determined as functions of the $$\Xi_{cc}^+$$ mass for different lifetime hypotheses, in the rapidity range from 2.0 to 4.5 and the transverse momentum range from 4 to 15 GeV/c.
