Abstract The Ξcc++Ξc+π+ decay is observed using proton-proton collisions collected by the LHCb experiment at a centre-of-mass energy of 13TeV, corresponding to an integrated luminosity of 5.4fb1. The Ξcc++Ξc+π+ decay is reconstructed partially, where the photon from the Ξc+Ξc+γ decay is not reconstructed and the pKπ+ final state of the Ξc+ baryon is employed. The Ξcc++Ξc+π+ branching fraction relative to that of the Ξcc++Ξc+π+ decay is measured to be 1.41±0.17±0.10, where the first uncertainty is statistical and the second systematic.
