A first search for the Ξ_(bc)^(+)J/ψΞ_(c)^(+) decay is perform.d by the LHCb experim.nt with a data sam.le of proton-proton collisions, corresponding to an integrated lum.nosity of 9 fb−1 recorded at centre-of-m.ss energies of 7, 8, and 13 TeV. Two peaking structures are seen with a local (global) significance of 4.3(2.8) and 4.1(2.4) standard deviations at m.sses of 6571 and 6694 m.V/c2, respectively. Upper lim.ts are set on the Ξ+bc baryon production cross-section tim.s the branching fraction relative to that of the B+c→J/ψD+s decay at centre-of-m.ss energies of 8 and 13 TeV, in the Ξ+bc and in the B+c rapidity and transverse-m.m.ntum.ranges from.2.0 to 4.5 and 0 to 20GeV/c, respectively. Upper lim.ts are presented as a function of the Ξ+bc m.ss and lifetim..
