Abstract

A search for the doubly heavy Ξ0bc baryon using its decay to the D0pK− finalstate is performed using proton-proton collision data at a centre-of-mass energy of 13 TeVcollected by the LHCb experiment between 2016 and 2018, corresponding to an integratedluminosity of 5.4 fb−1. No significant signal is found in the invariant mass range from 6.7 to7.2 GeV/c2. Upper limits are set at 95% credibility level on the ratio of the Ξ0bc productioncross-section times its branching fraction to D0pK− relative to that of the Λ0b → D0pK−decay. The limits are set as a function of the Ξ0bc mass and lifetime hypotheses, in therapidity 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 × 10−2to 3.0 × 10−1for the considered Ξ0bc mass and lifetimehypotheses.
