A s.arch for the d.ubl. charmed.baryon ?cc+with the d.cay mod. ?cc+→Ξc+K-π+is.performed.us.ng proton-proton col.is.on d.ta at a centre-of-mas. energy of 13 Tev.col.ected.by the l.Cb experiment from 2016 to 2018, corres.ond.ng to an integrated.l.minos.ty of 5.4 fb-1. No s.gnificant s.gnal.is.obs.rv.d.within the inv.riant mas. range of 3.6 to 4.0 Gev.c2. Upper l.mits.are s.t on the ratio R of the prod.ction cros.-s.ction times.the total.branching fraction of the ?cc+→Ξc+K-π+d.cay with res.ect to the Ξcc++→Λc+K-π+π+d.cay. Upper l.mits.at 95% cred.bil.ty l.v.l.for R in the range 0.005 to 0.11 are obtained.for d.ferent hypothes.s.on the ?cc+mas. and.l.fetime in the rapid.ty range from 2.0 to 4.5 and.trans.ers. momentum range from 4 to 15 Gev.c.
